I agree. Love Trespass. From the acapela opening to the closing notes of The Knife, just excellent. Yes the drumming would much improve going from Mayhew to Collins; although I don’t find anything particularly weak about Mayhew’s drumming on this album. I’m always impressed that a group of 20 year olds, could write music this well. It’s quite amazing.
I love it but it's simply too old, poorly produced, even by the standards of that time, particularly considering what bands like Yes were doing. Poorly arranged, some dodgy lyrics and the musicianship simply isn't there.
I doubt anybody listening to this album today for the first time could get into it. Still, when stripped down to the core: chords, harmony and melodies the songs are very good. The talent was obviously there, the originality undeniable and the overall atmosphere is pure magic.
