Yeah, all _four_ of the Depth Charge cd comps are essential, and what's more, readily available from Submerge as far as I know. The Tresor comps (up to 5 or 6) have consistently solid contributions from various Detroit artists.
Make sure to grab 'Generator World Sonik Domination' Volumes One and Two if you get half a chance. 'Made in Detroit' is also well worth tracking down.
