John Dworkin has an interesting editorial about a confrontation between Gary Peacock and Elvis Costello at the Iridium in New York City entitled The Trouble With Gary: An Open Letter to the Jazz Community:
Soon thereafter, Bill Milkowski quoted Peacock as saying, “I don't play backup to no rock star,” in JazzTimes magazine. I was and am personally offended and embarrassed by Peacock's shameless public display of musical elitism. Also, his use of the term “rock star” most likely hints at his lack of familiarity with Costello's music and career as that term doesn't really fit, but this is a relatively semantic point.
