Concert Bootlegs
(noworriesto.day)
I've had good luck of finding very good concert recordings—many are recordings from the mixing desk tape outs as 24/94 .FLAC-s with excellent sound quality—from Internet Archive. The search system is tedious, though, and you probably won't find "big acts" there. But if your tastes include modern jazz, folk and indie rock, it can be a treasure trove.
