As if familiarizing oneself with and identifying various genres like house, drum ’n’ bass, dubstep, trap, jungle and breakbeat were too, I don’t know, exhausting for everybody, the world has now settled on the catch-all phrase to end all catch-all phrases for electronic dance music: EDM. Which means, uh, “electronic dance music.” Vague, isn’t it? Indeed! (Which might explain why it’s so useful as an attraction to the masses.) Before our genres get ever more vague, until we just call everything “music,” Dennis the Menac3, Elbyne, Rule 62 and That Sober Kid Feenix play an EDM party on Saturday, Feb. 1, at the Phoenix Theater. 201 E. Washington St., Petaluma. 8pm. $10. 707.762.3565.
