Remember when Burke left Cristina at the altar at the end of season three of Grey’s Anatomy? Of course you do, because that’s when you first heard the sweet, sad crooning of Ingrid Michaelson. When the TV show’s music scouts found Michaelson’s MySpace page, the young Staten Island native was an unknown teacher at an afterschool theater program and living with her parents. On the execs’ request, she wrote “Keep Breathing” for the show, and in short order, another song appeared in an Old Navy commercial; she released an album on her own label and garnered comparisons to Lisa Loeb and Norah Jones. Then her second album, Boys and Girls, landed on the Billboard charts, making her the only unsigned artist with Billboardworthy record sales. Now she’s fresh back from a European tour with Jason Mraz and making the rounds in the US. She stops at the Paradise Rock Club (967 Comm Ave, Boston, 617.562.8800) tonight at 9 p.m.; doors are at 8.
