I forgot what date the concert took place, but I love the setlist and performance.
It seems to me, though, that in the bootleg I have, Freddie's vocal sounds strangely high... (and unusually high-pitched) - is the recording somehow accelerated?
April 28th. For the first several songs, I believe the pitch is a semitone too fast. From Liar onward, it's a semitone and a half too fast. Adjust accordingly if you can, with a wave editor. Hope this helps!
