Hmmm... that sounds suspiciously like an order. Why don't you just try googling them? Phil Spector made a career out of producing "wall of sound music" like that (and also produced the Beatles' Let It Be later on in his career). Buddy Holly was moving in that direction in the late 50s, shortly before his death, as evidenced by his last few singles.
