Jon Brion used to hold regular sets at the Largo Club in LA, and very often special guests would open for him and/or join him on stage.
Tonight, the special guests were Beck and Beth Orton. In between Eleni Mandell's opening set, and Jon Brion's own, Beck, Orton and Brion played for an hour, mixing Mutations songs with Orton's songs (and some requests).
(Fiona Apple performed during Brion's set.)
Have been unable to find much more than this, unfortunately, like what songs they did or anything. The Largo was pretty tiny back then, and not many people were likely there.
