I definitely recommend "Queen Rock Montreal & Live Aid" as an excellent title to rock out to
Originally released in theaters as "We Will Rock You" - for the bluray, the original 35mm negative was scanned and the soundtrack was remastered in DTS HD 96/24 from the original multichannel tapes. It looks AMAZING for something filmed in 1981.
The Live Aid footage isn't quite as amazing technically, but it looks and sounds better than you've ever seen it.
