Maybe the reason is they're not good enough quality at the time, but now stuff is thin on the ground than its time to get them out there. I've got shows I recorded that suffer issues and hence didn't take any priority. However Digital 8, MicroMV tapes still need transferring and the hard disks that some of the HD recordings are on could fail and be lost forever.
The only time I didn't share something was with a german taper called Olli? who for some reason I was pissed off with some weird reason that I've long since forgotten when he was after the Paris show. If he wants the source for another remix then get in touch.
Hopefully, some peeps can vouch for my openness in sharing and contributing to sharing (for free) the love over the years.
