It’s nothing for a global conglomerate like Sony to have record labels and moviemaking companies among its holdings — and to be equally invested in manufacturing noise-canceling headphones and digital cameras. But Brendan Benson — longtime power-pop troubadour and sometime Raconteur — is the little guy who’s really and truly going out on a limb. The first phase of his plan was Readymade Records and Publishing, a way to get his new music out there, along with good stuff by Young Hines, Cory Chisel and other acts he digs. Instead of building a staff, Readymade contracts with folks to work individual projects on commission, which is something kinda different. So is phase two: Readymade Films. That’s the reason for this particular party. Benson will be screening a live performance film — Concert Los Angeles — that he shot when he was touring with Brad Pemberton, Jon Auer and Ken Stringfellow a couple of years back, and he’ll be doing a DJ set. Plus the bluesy string band The Howling Brothers — one of the newer editions to the Readymade roster — will be on hand to share some of their savvy showmanship.
