Backstage riders are often the stuff of legend and speculation — just ask any rock music fan about Van Halen’s aversion to brown M&Ms. (Granted, they did have a sound reason behind the demand that had nothing to do with color preference.) For those who are curious to know the behind-the-scenes quirks of the Killers, Foo Fighters, John Mayer, or Amy Winehouse, The Smoking Gun has compiled an online archive of tour riders from 220 acts and counting. There’s a little something for everyone (the list categorizes acts by genre) and each document makes for fascinating reading — point five on page three of the Beatles’ 1965 rider, for example, states that “artists will not be required to perform before a segregated audience.” And for sheer comedy, the rider for Iggy & the Stooges is not to be missed. Pity the poor soul who reads through its 18 pages to find this addendum waiting for them.
