It's easy to poke fun at the Disco Biscuits (trance fusion? ugh). Still, bisco music (as they call it) remains a huge hit among the jammy throngs, and apparently the fan base is growing. The prolific band Philly settles in for a trio of NYE-pegged shows, culminating in a three-set Dec 31 performance. Modern Measure opens Dec 29; TAUK opens Dec 30.
