Sleigh Bells were one of the breakout acts from last year’s CMJ Music Marathon, and were named one of 2010’s Top Artists to Watch in many publications. The duo recently signed with M.I.A.’s N.E.E.T. imprint and last week she announced the release of their debut LP via her Twitter, which has quickly become her preferred method of communicating with the press. The album is called Treats and will be out May 11. “Tell ‘Em” is the first single and it’s currently available as a free download over on what appears to be their official website, which judging by the look of things, may have been designed by M.I.A.’s art team (epileptics beware).
