Alt-J (sometimes stylised ∆) was formed when Gwil Sainsbury (guitar, bass), Joe Newman (guitar, vocals), Gus Unger-Hamilton (keyboards), and Thom Sonny Green (drums) met at the University of Leeds, Leeds, UK in 2007. The band currently resides in Cambridge.
These are videos from concerts where alt-J played, so they may be of other bands that played the concert as well.
