"Roger Waters' "The Wall" is a favorite of mine, musically and sonically. Powerful bass, explosive dynamics, and an incredibly immersive soundstage due to the processing. This is a recording I've used to test the imaging mettle of many a speaker (Prime Towers nail it!), and with a capable system, it throws a huge picture over a full 180 degrees with incredible details and nuance that send shivers down your spine. It's recently been released on Dolby Atmos, which sounds absolutely incredible.
