Jack Nitzsche is such an undersung legend…Buffalo Springfields “Expecting to Fly” is pretty unbeatable too. Others that come to mind: Van Dyke Parks’ “Song Cycle” album is so chock full of inventive orchestral arrangements, so intimidatingly clever, almost made me want to give up at one point
David Axelrod (“The Edge”) and Dexter Wansel (“The Sweetest Pain” “Nights Over Egypt”) arrangements also top my list
