"Happy" is the first piece of music to be released from the upcoming album "GRRR Live!" - the definitive live greatest-hits collection from The Rolling Stones. Recorded during the band's "50 and counting" anniversary tour in 2012 in Newark, New Jersey, the audio has been re-edited and remixed, including Dolby Atmos. The complete "GRRR Live!" project will be released on February 10 and features an incredible line-up of guests supporting the band - The Black Keys, Gary Clark Jr, Lady Gaga, John Mayer, Bruce Springsteen & Mick Taylor. Mercury Studio will release "GRRR Live!" not only on audio, but also on audiovisual formats (Blu-ray and DVD). The full concert had not been available since its pay-per-view broadcast in 2012 - a welcome addition for fans.
