Surprising Backing Bands

A recent thread mentioned Meat Loaf's "Bat Out of Hell" and reminded me that the backing band behind Meat Loaf included Todd Rundgren's Utopia, Max W and Roy Bittan from Bruce's E Street Band, Edgar Winter, and, of course, Phil Rizutto. Steven Stills' first solo record included Clapton, Jimi, and a host of others.

I was wondering which other records might be notable for all star backing bands, particularly where they might be unexpected or not well known.
