Dirty Projectors is a band led by a guitarist/composer named David Longstreth. Ezra Koenig, the lead singer from Vampire Weekend, has played saxophone for the Dirty Projectors.

Longstreth’s band was known for it’s artiness, but in 2009 it released an album called Bitte Orca, which used African-style guitar lines and the harmonized vocals of three young women to create a pretty wonderful and warm art-pop sound. This album was in heavy rotation at my house, and listening again I’m struck by how different the Dirty Projectors used somewhat similar sounds as Vampire Weekend, to strikingly (to my ear) more interesting and agreeable effect.
