Man, that hits close to home. I've got a guitar gathering dust in the corner (bought it with big dreams, of course). Practicing for years without a real gig can feel like running in place. At least the commute has a good soundtrack, right?
Back in my garage band days, we called the commute our 'world tour'. It was the only time we had a captive audience, even if they were just other drivers. Now I realize those rehearsals were just for the car stereo.
