Harmonica player and vocalist Sugar Blue doesn’t like anyone telling him what to do or how to do it. While this Harlem-born musician has done classic low-end-of-the-harp work for the Stones, Dylan, and Willie Dixon, he’d rather lead his own band, write his own songs, and accentuate less traditional, noisy, high-end blowing. On In Your Eyes, that means New Orleanslike laid-back funk, dramatic ballads, and bombastic blues-rock with lyrics that mention gold cards and the federal deficit while still maintaining traditional blues themes. At 9:30 p.m. at Tornado Alley, 11319 Elkin St., Wheaton. $9. (301) 929-0795.CP
