Sub - In Concert. 1971 Germany
CD reissue: 1994 Penner / Garden of Delights
LP reissues: 2004 Mayfair; 2012 Garden of Delights
In a nutshell, Sub is a Krautrock version of Deep Purple. Which works real well for me, especially these days. Long tracks with intense solos, but with that Germanic vibe not present with Lord and Blackmore. It's not a live concert, though it plays like one, and perhaps that's why they went forward with the idea. For this kind of album, Sub is top of the class.
My first copy was actually the reissue LP from a few years ago, but I recently sourced the CD (original on Penner). Since it's the same in every way, I decided to cut the one that occupied the most space.
