Lil Ed Williams might play the blues but he decidedly steers clear of clichés about being broke and desperate. Rather, the guy revels in letting the good times roll. For the bulk of his career, which started back in 1986 with his appropriately titled debut Roughhousin’, Williams has embraced blues’ rowdy, roadhouse side. A 2012 effort, Jump Start kicks off with “If You Were Mine,” a high-octane number for which Williams cranks up his guitar, and never lets up as Williams indulges in a little Stevie Ray Vaughan-like blues on “Kick Me to the Curb” and consistently keeps the energy level high. On tour in support of its latest effort, The Big Sound of Lil’ Ed & the Blues Imperials, the group performs tonight at 8 at Music Box Supper Club.
