Underbombers / Fanatik bootleg cassettes

A couple of weeks ago 12ManRambo had this ebay auction including a batch of mysterious hand dubbed cassettes full of supposedly unreleased music from San Jose collective Underbombers (Sub Contents, Zest) and producer Fanatik.
I was able to score 3 of those tapes:

"Phanatik Conception" (pic above), contains a lot of known Fanatik instrumentals from the Beat tapes era but this time with MCs on them... I never heard any of those versions (maybe I missed some releases?).
They sound at the same time solid enough to be officially released but you can also hear that it's straight from the studio takes (emcees commenting before and after etc.). Second track for example is Dave Dub over the "Parallel" beat. There's a MC I couldn't name on the first track rapping over "Night Terror"; a nice short collage interlude I never heard; a track with a female singer...
On the B side it's 6 full tracks of known Fanatik beats with Grand the Visitor from Homeliss Derilex rapping on it, and a cameo by Persevere on the last one. Pretty nice!

Second tape is by Zest the Smoker. It features some instrumentals, two versions of My Ol Nasty Habit, one over a different beat than the one we know, and the second one is an alternate vocal take on the original beat. Then Encore's "Think Twice". On the flip there's a 23-minute long freestyle featuring Persevere, Clishe and some other guys I couldn't name. It's called "Freestyle @ Steve's Bachelor Party".

"Subconscience" starts with a freestyle by Dave Dub & Persevere, then some known instrumental by Fanatik, My Ol Nasty Habit by Zest, then more freestyle by some guy I couldn't name, Zest, then some more freestyle by Persevere and finally a radio cameo with an extended freestyle over several instros by both Sub Contents members.
