Beck Plays Surprise Opening Set For Beth Orton

"Beck, Beth. Beth, Beck."

That was probably how the introductions went on Tuesday night before Beck played a surprise opening set for Beth Orton's show at the El Rey Theater in Los Angeles.

Orton's publicists confirm that the uber avant gardist did indeed jump onstage at the El Rey and perform several songs from his recent disc, "Mutations," a record that Beck has sued Geffen Records for releasing (see "Beck Sues Label For Copyright Infringement").

Billed as "Silverlake Menza," Beck borrowed a guitar and harmonica from Orton and belted out "Tropicalia," "Nobody's Fault But My Own," "Cold Brains," and "Lazy Flies."

As for Orton, the folky torchsinger will be in Vancouver, British Columbia today to help Lilith Fair kick off its final outing. Orton will stay on the female music fest for the next two weeks, wrapping up her stint on July 17 at the Rose Bowl in Los Angeles.
