Van Halen had a notable effect on the modern rock music tour with their use of the concert technical contract rider. They were one of the first bands[citation needed] to use contract riders to specify a "wish list," a practice now used throughout the music industry. They pioneered extensive requirements including power availability and stage construction details. The band's demands were not limited to technical issues; their now-infamous rider specified that a bowl of M&M's, with all of the brown M&M's removed, was to be placed in their dressing room.[79] According to David Lee Roth, this was listed in the technical portion of the contract not because the band wanted to make capricious demands of the venue, but rather as a test of whether or not the contract had actually been thoroughly read and honored, as it contained other requirements involving legitimate safety concerns.[80] If the bowl was present, then the band members could safely assume the other, legitimate, items in the technical rider were being fulfilled to their satisfaction. Conversely, if the bowl was missing, or brown M&M's were present, then the band members would be within their rights to have the venue inspect the work, ask it be redone, etc.[81] Their concern for safety was real: during their earlier tours, not only had equipment been damaged, but several members of their road crew were nearly electrocuted, both due to inadequate safety measures and preparation on the part of the local venue.
