Big orchestral sound in pop, rock etc.

Most of the times pop, rock, soul etc. music is done by the same basic band (guitar/bass/drums) and one or more singers. Now I´m looking for albums that go bigger, where the band uses more musicians to produce a bigger sound. I´ve always been a fan of Elvis´ early 70s live albums and recently came across a few more live albums that may not share the same musical sensibilities, but which have a big orchestral sound: More people playing instruments, more background singers, full stage, full sound. I like that. Maybe you know a few more examples of musicians and bands that dared to go big. I don´t neccessarily mean the “XY plays his old hits with an orchestra“-thing even though that can result in great recordings too. Here are some big sounding albums I like:

Joe Cocker – Mad Dogs and Englishmen
Procol Harum – Live in Concert With The Edmonton Symphony Orchestra
Elvis – All the big Vegas shows from the early 70s
Sufjan Stevens – Illinois
Chicago – First few albums (still working my way through them)
