Named in honor of the original Electric Factory, which opened in 1968 and hosted acts ranging from Jimi Hendrix to the Grateful Dead, the new venue is in a cavernous former warehouse just north of Center City and presents mainly alternative rock bands. It has a capacity of about 2,500, but that number mostly refers to standing room; the main concert area doesn't have seats, although you can sit down at a balcony bar and watch the proceedings from there.
