The Who Live At Leeds "Magic Bus" fits the thread here well.
Guilty pleasures
Recently I picked up a copy of Aerosmith's OH YEAH: ULTIMATE HITS on SACD. It's actually a good study of how recording techniques have changed over the years, as comparing 70s tracks with stuff from the mid-90s makes clear. Anyhow, I found myself strangely drawn to their remake of "Walk This Way" with Run-DMC. The soundstage is tiny but perfect, with all the hiss, grit, and grunge of the original. As I was enjoying this guilty pleasure, I was wondering which ones others might favor. What's your favorite greasy, non-audiophile-approved, makes-you-smile recording?
