The most interesting bits are the John and Reni jam. Everyone knows John is a bit of demon on the guitar (it's hard to miss it the way Second Coming is produced), but Reni's skills are often under appericated. Breaking Into Heaven is interesting too; there's no guitars but there is some popcorn-esque synth parts. I'm fairly sure that this incarnation of BITH is where Ian got the loops for Can't See Me from.
The sound quality is pretty good, but not perfect. It sounds like its been transfered from a tape. There are a few drop outs here and there but it's perfectly listenable.
