I've never sat and listened through all of Rumours. I need to give a complete listen through one of these days.
I always found it hard to enjoy Rumours. (great production and vocal harmonies but that rhythm section. Oh dear, no.)
I'm currently listening to
DT: D/T
Haken: The Mountain (what a dense album this is, wow. Boom. Very basic as compared to present-day DT though, but also very different and far more emotional IMHO.)
Frank Zappa: Jazz From Hell
Frank Zappa: Shut Up N Play Yer Guitar
Frank Zappa: London Symphony Orchestra
