I once bought a load of burnt CDs from Ebay around that time, mixes from the Delta Heavy tour , Manumission, Bedrock nights…all S&D . Propper dodgy, but they were superb. Never to this day found the mixes online.
Suppose a lot of live mixes in that era were dry runs for the GU / Renaissance/ mix CD releases, so were kept on the down low so as not to cannibalize those sales (?)
