Peter Mulvey is always up to something.

For two decades, the Milwaukee singer-songwriter has been playing shows, making records, biking to gigs across the state and around the country and honing his guitar, songwriting and performing chops.

We recently told you about Mulvey's latest CD, "Letters From a Flying Machine" prior to his gig last month at The Pabst Theater. Recently, Mulvey sat down for an extended conversation with our friends from Mindpool TV as part of their "Sound Pass" series. The interview was so cool that we thought it would be good to share it.
