Hi all, Anyone familiar with these bootleg releases? Bought them maybe 10 years back at used record stores in MA and NH. Boygroup, Zoocoustic, and Rock. Boygroup is recorded in Berlin November 4th, 1981 Zoocoustic is through the ZooTV and associated tours and says it's soundboard recordings. Rock is Rotterdam July 18th 1997, and is apparently an "enhanced" CD that has "TV Footage" from the concert as well. Images: https://imgur.com/a/TSfeXBa
Those would all be audience recordings in which U2START members would be familiar. The more well known the broadcast, the higher chance it was bootlegged.
