The Allman Brothers Band will return to New York’s Beacon Theater, site of a two-decade run of annual concerts, for eight gigs in March.The Georgia band was ousted from the venue in 2010 by an engagement of the Cirque du Soleil show “Banana Shpeel,” which shuttered quickly. Group was forced to relocate its dates to the United Palace. Venue shift created an outcry among hardcore Allmans fans, who had trekked to the Beacon annually since group’s reformation in 1989. Act has sold out the 2,900-seat theater 188 times. MSG Entertainment, which manages the Manhattan theater, announced the Allmans’ return at a Monday press conference, noting the act will be “back at the Beacon, where they belong.” The March 10-19 Beacon run will coincide with the 40th anni of band’s historic March 12-13, 1971, shows at New York’s long-defunct Fillmore East, heard on the Allmans’ breakthrough double live set “At Fillmore East” that year.
