The recording academy and Grammy producers have unveiled a flurry of Grammy performers this week, beginning Tuesday with a return to the stage for Adele and a Katy Perry announcement on Wednesday. Thursday, the curtain was pulled back on one of the telecast’s rock ‘n’ roll acts: Bruce Springsteen and the E Street Band, who are gearing up for a new tour. Springsteen isn’t nominated for any new works — “The Promise: The Darkness on the Edge of Town Story” is, however, in the running for best boxed or special limited edition package — and instead has a new album in “Wrecking Ball,” due March 6, to promote. The upcoming tour with the E Street Band will be the act’s first since the passing of his former band mate, tenor saxophonist Clarence “Big Man” Clemons. While the performance wasn’t announced as such, the Grammy telecast is typically loaded with high-concept medleys and pairing, and it wouldn’t be out of the realm of the ordinary to expect Springsteen’s appearance to include a tribute to his late collaborator. Clemons, whose best-known work can be found on numerous Springsteen staples, including “Born to Run,” “Jungleland” and “Rosalita,” died in June at a Palm Beach, Fla., hospital of complications from a massive stroke he suffered at his Florida home. While Clemons had worked with the likes of Jackson Browne, Ringo Starr, Aretha Franklin and Lady Gaga, among many others, he is most closely associated with Springsteen and E Street Band. As announced, Springsteen will play a string of dates in the U.S. on his 2012 tour with the E Street Band ahead of shows in Europe, starting March 18 in Atlanta.
