Telefon Tel Aviv is a New Orleans, Louisiana-derived, Chicago, Illinois-based American electronic music act, formerly comprising Charles Cooper and Joshua Eustis. Telefon Tel Aviv continues with Eustis as the sole official member since Cooper's accidental death in 2009 (an event often falsely reported as a suicide). Eustis is also known for being a member of the most recent lineup of Puscifer and Nine Inch Nails' live performances.
