Isaac Castor – “The Rabbit Hole 3: Smoking Caterpillar” review

Detroit, Michigan emcee Isaac Castor returning after 2 years for his 3rd full-length studio album. Coming up in 2010 under the original moniker Gameboi, he would go on drop 4 mixtapes & 3 EPs prior to signing to the local underground hip hop powerhouse Middle Finger Music following its formation 8 years later. He then enlisted the label’s co-founder Foul Mouth behind the boards for his full-length debut The Rabbit Hole & the sequel ahead of the trilogy chapter Smoking Caterpillar.

“Here They Come” is this boom bap-driven opener tryna get the money while he’s still here & assuring that he ain’t ever behind whereas “I Ain’t Fresh?” keeps it in the basement instrumentally dropping off battle bars for a few minutes. “Blind” has a soulfully & jazzier vibe talking about finally living in the mountains leading into “Why Should I Die?” hops over some horns, kicks & snares to call himself a diamond in the sky.

Kain Cole joins Isaac on “Cash Rules” planting the seeds whilst everyone else is camping while “Sidetracked” talking about all these other MCs selling out instead of him & refusing to do so. “Customer” maintains a boom bap edge promising 2025 gonna get ugly just before “Shadow Realm” featuring J-Classic & Mvck Nyce bringing the trio together so they can all flex their pen-game.

“Time for Jazz” hooks up a crooning sample talking about ditching the lazy habits he used to have, but then “Gotham” compares himself to Batman here to save the city. “Spin Itch” heads for more of a rap rock direction feelin’ cold blooded while “No Comp” featuring Jalen Frazier & Tone Plummer reminds everyone that you play by the rules if you in the game.

The song “Thoughts Runnin’” nears the end of the final chapter in the Rabbit Hole trilogy Smoking Caterpillar promising that he’ll break your head wide open so he can examine the contents of it while the closing track “Live Wire” aggressively rounds it out talking about going through the cycle all over again in the midst of him growing.

This upcoming spring will mark the 5 year anniversary of The Rabbit Hole in addition to the sequel turning 2 a couple weeks from now so whether Isaac intends on continuing the series with a Rabbit Hole 4 or a completely different body of work within itself, The Rabbit Hole 3: Smoking Caterpillar takes everything that made both of it’s predecessors the most essential listens in Isaac’s discography & elevates them. Foul Mouth builds his production around boom bap, jazz rap & rap rock with Isaac’s lyricism going from hardcore to introspective.

Score: 4.5/5

Isaac Castor – “The Rabbit Hole 2” review

This is the long-awaited sophomore album from Detroit emcee Isaac Castor. Coming up in 2010 under the original moniker Gameboi, he would go on drop 4 mixtapes & 3 EPs prior to signing to the local underground hip hop powerhouse Middle Finger Music following its formation 8 years later. He then enlisted the label’s co-founder Foul Mouth behind the boards for his full-length debut The Rabbit Hole a month after the world stopped due to the COVID-19 pandemic & both parties are reuniting to deliver a sequel in light of the predecessor’s 3-year anniversary in just a couple months.

“The Sequel” is a psychedelic boom bap opener with Isaac responding to those asking where he’s been all this time prior to Marv Won assisting him on “75 South” talking about how nobody puts it down the way they do accompanied by some keys, kicks & snares. “Eye See” has a more sample-based sound basically touching on life being as wonderful as it is & destined for greatness leading into the dusty “Admit It” comparing his raps to that of pure, uncut coke.

Moving onto “Tourniquet”, we have the Gameboi over a darker instrumental talking about pulling up to murder shit just before Jypsy tags along for the bluesy “Vamanos Pest” dropping some lethal bars for anyone who dares to step up to either one of them in a rap battle. “Nosebleeds” dives into more jazzier territory encouraging the goofy asses to walk back, but then “Cliffhanger” returns to the boom bap once again getting loose at the venues they shut down.

Dango Forlaine & Ronnie Alpha both tag along for the cutthroat “Napalm 8Ball” so all 3 MCs can flex their lyrical prowesses while “Smoke All Night” switches things up with a mystic trap beat & the subject matter of Isaac professing his love for weed is relatable to any stoner including myself. “Power of the Mind” instrumentally has a bit of a J Dilla influence to it advising that one is unable to front on titular topic while “Riddim” with Bang Belushi has a woozily dope sample flip as the pair go on to belittle their opposition.

Meanwhile with “Fall from Grace”, the production & DJ Skyrah’s hypnotic chorus give me quite a bit of Portishead vibes setting the course for Speak of the Devil’s upcoming debut as Xtra Overdoze joins Isaac talk about being stitched together kin to pain & pleasure while “Grand Prix” with Fatt Father & Guilty Simpson is a rock/boom bap crossover with a Pink Floyd sample toasting champagne off the Grand Haven Pier as long as his people are by his side. The song “Studio Vibe” with Bizarre is a mellower cut bringing exactly that while the crooning penultimate track “Still in the Hole” admits he’s finding the steps to climb out to the hole he’s still in. “Yes (Intro in Reverse)” comes through with a horn-inflicted closer attacking wack rappers 1 last time.

Considering the 3 year gap between this & the Gameboi’s full-length debut, it had me anticipating to hear how much dude has grown as artist since then & I happen to enjoy this sequel as much if not more than predecessor. Isaac sounds even hungrier than he did last time with the features all being as well-picked & the production that Foul Mouth cooks up is more eclectic in sound from boom bap to jazz rap & trap. Middle Finger Music always has something exciting going on & The Rabbit Hole 2 is just the beginning of their 2023.

Score: 4/5

Isaac Castor – “The Rabbit Hole” review

Isaac Castor is a 24 year old rapper from Ann Arbor, Michigan who I first caught wind of through his association with Middle Finger Music a few years ago. He eventually landed a contract with the label & now he’s hooking up with it’s co-founder Foul Mouth for his full-length debut.

The album kicks off with “Homesick”, where Isaac talks about how he’s ready to take over the game & I love the meditative boom bap production as well. The next song “Retrospect” with Bub Rock sees the 2 reflecting about their past & how they’re doing better now over a beautiful soul sample while “The Sickness” charismatically shows off his skills over an organ-inflicted boom bap beat. The song “Regal” talks about how raw his music is over an instrumental that sounds like something RZA would’ve made in the 90’s while the track “Fire Drill” talks about being built for this over a jazzy boom bap beat.

The song “Headless Horsemen” with Fatt Father & J-Classic sees the 3 challenging their competition over a boom bap beat with a psychedelic guitar lead while the title track talks about partying over a woozy beat. The song “Name 5 Songs” talks about groupies over a fast-tempo trap beat while the track “Guess What?” talks about this girl he was seeing running off with another guy over a funky beat. The song “That Ain’t Love” pays tribute to those who’ve been heartbroken over a boom bap beat with some somber piano chords while the track “Paramount” with A-Minus sees the 2 talking about earning their stripes over an upbeat instrumental.

The song “Green Pill” with Aztek the Barfly sees the 2 talking about how no one’s on their level over a suspenseful instrumental while the penultimate track “Can’t Decide” talks about his demons over some strings. The album finishes off with “Challenged”, where Isaac talks about being blessed in the moment over an energetic beat. There is a bonus track worth mentioning called “Excuse My English” referencing UFC President Dana White.

What a fantastic debut. Foul Mouth reminds us why he’s my favorite producer out in Detroit with his versatile sound whereas Isaac really shines on here as his pen-game sounds smarter than ever & you really get a good look at who he is as a whole. Really looking forward to watch him grow in the future & to see what else Middle Finger Music has in store for the new decade.

Score: 4/5
