Dick PrallIt's been more than two years since Dick Prall released his last studio album, Weightless, and while that's a typical gap in the music business, the Iowa-raised, Chicago-based singer/songwriter doesn't believe it works for independent artists generally, and him particularly.

"For me, it's kind of daunting to say, 'Okay, this is what I've done the last two years, here you go, and let's see if that carries for the next two years,'" he said in a recent interview to promote his September 9 solo-acoustic show at the Redstone Room. (He'll also be recording a Daytrotter.com session that day.)

The problem, he said, is that schedule forces a musician to re-build momentum with each album. So he's determined to stop fizzling between releases. He's prepping an EP for this fall, with another to follow in late winter.

In this new age of singles (and single-track purchasing), the EP looks to Prall like an ideal format.
