Black Hole has been again compiled by Mikko Mattlar, whose encyclopedic knowledge in the field of Finnish electronic music produces 20 cuts of electro-cult has helped him dig up 20 cuts of rare groove from obscure regional compilation records, seven inches of which only a test pressing exists, demo tapes and privately financed singles. Stylistically the compilation moves from 1979 disco funk as performed by Peak Funktion on their unreleased record to homebrewed synth visions by late 80's bedroom wizards.

Interesting curiosities among the 20 tracks include the riveting dance number by Jarkko Väljä, who received some fame back in the day as a Michael Jackson impersonator, and released one 7" single, that has become an expensive rarity. Another thing you wouldn't believe existed at all if it wasn't included here is "Israel Is Real" by We, a short-lived gospel vocal quartet, accompanied here by a drum machine and a synthesizer, which makes for an unforgettable and surprisingly catchy four minute piece of underground gospel disco from 1983.
