If you lost track of Billy Bragg in the mid-’80s, when he provided ideologically minded college kids with an agenda for social rebellion, it would be a good guess he has spent the last 10 years plotting covert operations for a political revolution. But somewhere in the late ’80s the activist discovered that life’s most complicated battles are fought in the bedroom. So it’s no great surprise to learn that Bragg’s been tending to his domestic duties since the 1991 release of Don’t Try This at Home. Word is that tonight Bragg will sample material from an album to be released later this summer, but let’s hope that between songs he also tackles some of those issues that hit close to home, like the masturbatory implications of guitar solos or the reasons that American rock fans generally prefer to hear about politics from the British. Smoke opens at 8:45 p.m. at the 9:30 Club, 815 V St. NW. $20. (202) 393-0930. (Brett Anderson)
