English indie rock band Alt-J is without its bassist, Gwil Sainsbury.
In a Twitter post early Saturday (Jan. 11), the rockers revealed that Sainsbury, the band's bassist and guitarist since its inception, was leaving Alt-J effective immediately. However, the tweet noted that Sainsbury's removal from the band was "purely a personal decision" and "as our best friend, we support him completely."
With regret, Gwil is leaving alt-J. This is purely a personal decision and as our best friend we support him completely.
