I'm currently reading a book about the history of the Lollapalooza tour: how it all came together in 1990/91, with lots of behind the scenes stuff and fun anecdotes from all of the bands involved. The book basically covers the first 7 years of the festival, with most of the focus on the original '91 tour and how it really exploded with the '92 version. Super enjoyable read, especially if you grew up during that era.
