Marc Maron may be best known for his brutally candid "WTF" interview series, but he's just as respected with a lone microphone as well. His acerbic stand-up has earned him two Comedy Central specials and a forthcoming scripted series, but perhaps the best place to see him is in the flesh onstage. Icehouse, 24 N. Mentor Ave., Pasadena. 6 p.m. Sun. $22.50. icehousecomedy.com.
