R.E.M. showcased its new album "Accelerate" (Warner Bros.) alongside obscure old songs during an intimate showcase for fans and media at the Apple Store on London's Regent Street. The gig, which will be available as an audio download from the iTunes Music Store at a future date, came just two days after the band played its first-ever show at London's prestigious Royal Albert Hall. After a May-June tour in the U.S. and Canada, R.E.M. returns to the U.K. in July for a headline slot at the T in the Park festival, followed by stadium shows in August. (Billboard)
