British rockers Alt-J have decided to continue as a three-piece and not replace recently-departed bassist Gwil Sainsbury.

The musician stepped down from the 2012 Mercury Prize winners in January (14), citing personal reasons for his exit, and after more than a month as a trio, remaining members Joe Newman, Thom Green and Gus Unger-Hamilton have chosen to keep the line-up as is.

The band is currently working on the follow up to 2012's An Awesome Wave and keyboardist Unger-Hamilton admits he and his bandmates have become comfortable as a trio.

He tells, "It's possible we'll have somebody to play with us on tour. But, as for the band, it'll just be us three."
