I've been listening to Iron Maiden's Rock in Rio album on loop for a couple of days (I'm learning a bunch of the songs), and it's such a great album. Really wide selection of their hits from across their career, some classics, loads of new stuff, some deeper cuts (the Blaze tracks). It sounds amazing, to say it was all recorded on a single night. Absolutely amazing album, I can't think of a live effort that I enjoy more.
