Beach Boys used the Wrecking Crew - the best of the best session players. BW was certainly a great arranger...but Tony Asher’s lyrics on Pet Sounds made that album special and far more adult/intellectual than Brian’s lyrics.
A friend is a Mastering Engineer who remastered “Pet Sounds” and gifted me a copy of that album and 28 of the BB’s hits - all sourced from the studio master tapes...and so many others incl Beatles, Who, Stones, etc...
Yes, Brian’s best productions 1965-67 were with the Wrecking Crew playing on the tracks.
