Underground at its very best, recorded in the summer of 1970 and released in 1971 as a small edition. The tapes were recorded very accurately in the well-known Munich Union-Studios by five top musicians and have been preserved undamaged to this day. Why the title "Sub in concert" for a studio album? The reason is quite simple: Applause was added to the first track, in order to create a live atmosphere. Highlight of the record is probably "Match I". But the other songs are convincing as well, e.g. the long "Sub Theme I (Sub in concert)", or the tranquil "Sub Theme II (Money Maker)".
