"Black Demons on Stage" was originally an LP bootleg (containing only the live '85 tracks); this CD obviously came much later and was done by different bootleggers. At least they didn't use the ridiculous cover of the LP version anywhere.
There are gaps between all of the '85 live tracks. "Mordor" has what sounds like vinyl surface noise at 1:38. After "Branded and Exiled," there's a short audio snippet of the band receiving a Metal Hammer award for the "Gates to Purgatory" album at this same festival.
The tracks from the 1981 demo (9-11) are too high in pitch; this is especially evident on "Hallow the Hell." Compare them to tracks 12 and 13 (which are the same recordings, just from a different source). "Warchild" has nothing to do with the later song from the "Port Royal" album. The bootleg lists the 1981 tracks as the "Rock from Hell" demo, but I've never seen this name used until recently and never in any official bio or history of the band; some stupid mp3-trader seems to have applied the compilation name to this demo.
Tracks 12-17 are the "Heavy Metal Like a Hammerblow" demo which compiled various '81 and '83 tracks. I have no specific date or location info for the live 1983 tracks. Note that "Adrian" has an intro, which I believe was cut when it appeared on the "Rock from Hell" comp. LP.
