Something Corporate singer Andrew McMahon started Jack’s Mannequin in an attempt to channel his emotions and try something different. He was then diagnosed with acute lymphoblastic leukemia just before the band’s debut album release. Fortunately, he was able to recover; since then, Jack’s Mannequin have created three successful studio albums. The four-piece group is kicking off their 2012 tour at Irving Plaza, in New York, on Feb. 8–9. Both shows start at 6 p.m. Two days passes can be purchased for $65.50; one day passes are $45.50
