Though Gen Y may be most familiar with his voice because of those Cuba Gooding Sr. Time Life infomercials, soul balladeer Jerry “The Iceman” Butler remains one of doo-wop’s most active ambassadors. Butler’s own musical career began against the backdrop of Chicago’s Cabrini-Green housing complex. He and Curtis Mayfield escaped the projects by way of The Impressions in 1958; the group scored its first hit, “For Your Precious Love,” the same year. In 1985 the Rock and Roll Hall of Famer entered politics in Chicago; he’s been a Cook County commissioner for 26 years. He’s been playing Valentine’s Day at Blues Alley even longer: This weekend’s set marks his 30th year performing for lovers at the Georgetown venue.

JERRY “THE ICEMAN” BUTLER PERFORMS AT 8 P.M. AND 10 P.M. FEB. 11-13 AND AT 7 AND 10 P.M. FEB. 14. AT BLUES ALLEY, 1073 WISCONSIN AVE. NW. $43-$92. (202) 337-4141.
