Sarah Rabdau (and 149 other Boston artists) team-up to interpret Beck's new "Song Reader" @ Somerville Theatre - 2/28

Pere Ubu's David Thomas once said something about how the Beach Boys' unreleased Smile album was the greatest album of all time because it only existed in the imagination of the listener. Now, that mischivous offspring of the Fluxus movement, Beck Hansen, has one-upped the Beach Boys by releasing an album that actually doesn't exist at all. Released in December of 2012, Beck's Song Reader is the first album to my knowledge to only be released as a book of sheet-music (released by McSweeney's), and the first to not only exist in the imagination's of its listeners, but via the interpretations of its listeners. In addition to the book, Beck also put up the website Songreader.net where fans can download sheet-music and upload their versions. Talk about crowd-sourcing. None of this really comes as a surprise from a guy who sounded so much like Serge Gainsbourg on 2002's Sea Change that he eventually scored the gig of working with Gainsbourg's daughter. To say that he likes to play in the spectrum of interpretation/ pastiche/plagarism/reappropriation would be an understatement, and so sharing that with his fans seems like a natural progression. Tomorrow night, 2/28, at the Somerville Theatre in Davis Square, 150 or so Boston musicians and dancers will come together to interpret the 20-song "album" in a two-hour performance that will be sure to intrigue both Beck fans and non-Beck fans alike. After all, this might turn out to not sound very much like Beck at all. A 50-person choir? Burlesque dancers? Sounds more like the kind of musical hot mess that is built precisely for a one-time only, no holds-barred performance.
