In the ´80s and ´90s, Vince Clarke and Andy Bell of the synth-pop act Erasure churned out a string of successful hits. (Who could ever forget “Chains of Love” and “Sometimes”?) But on their latest release, the powerhouse dance duo has broken their musical chains and gone acoustic. For Union St., the two picked 11 lovelorn tracks from their vast 20-year discography. They then reconstructed them with pristine and harmonious acoustic strings, piano and percussion.

Today at Erasure’s acoustic performance at Cullen Theater, lucky showgoers will have a chance to hear these beautiful ballads in one of the city’s classiest venues. People who dismissed Erasure because it was “dance music” should check out their new orchestration and striking harmonies. Welcome one of dance’s biggest bands ever with open, loving arms.

Mon., May 8, 8 p.m.
