Their best album up to that time. I guess they topped it later. But only just. I just heard Elanor Rigby on the car radio today. It was overplayed at the time and there was such an inundation of Beatles then, that one sort of shrugged it off. But after not hearing it for years, it is diabolically brilliant to me. The string arrangement courtesy of George Martin really illustrates what serious musicianship means. McCartney's other flops like Hey Jude and Fool on the hill are inspired. He must have made a deal with the Devil to come up with that stuff. Obviously broke the deal after the Beatles broke up.There's an excellent reason they never played songs from Revolver during concerts.
Most of the big songs on Revolver were virtually impossible for the four of them to recreate on stage. Got To Get You Into My Life, For No One, Eleanor Rigby -- these songs all required horns and strings. No bands at the time brought back-up performers with them.
Songs like Tomorrow Never Knows requires use effects that they couldn't reproduce on stage. Remember, it was just four guys playing guitars, bass and drums -- that's it.
Revolver was a super complicated album for its time.
Rolling Stones fans take note.
