“The wizard” has been ripping and posting tapes daily on his https://terminalescape.blogspot.com blog since 2009. This massive collection covers DIY and underground releases from punk, hardcore, and all related and unrelated genre. There are both demos from contemporary bands and rare tapes, bootlegs, compilations, etc from his own personal collection, which is extensive due to his long-standing participation in undergound tape-trading scenes.
