If you’re a musician who has struggled through years of penny-pinching poverty, vermin-infested clubs, and shiny false promises just to catch that big break, do yourself a favor and stop reading this now. Hagerstown, Md.,’s Foam is that one-in-a-million success story that amazes many but sickens most. Led by 23-year-old singer-songwriter Jason Teach, the hard-rockin’ quartet landed a major deal with Epic without ever having toured outside the state. After listening to a few of Foam’s tunes, producer Michael Beinhorn (Soundgarden, Soul Asylum, Red Hot Chili Peppers) agreed to work with his first unrecorded rock act. But that’s just the good news. The deliciously bad news? Foam is a lousy Live knock-off at best, and despite their good fortune, Teach & Co. will have to work a helluva lot harder if they want to keep living the good life. With angry ska band the Ernies and Earth to Andy at 9 p.m. at the 9:30 Club, 815 V St. NW. $5. (202) 393-0930. (Sean Daly)
