Weather permitting, a walk down Burlington’s ChurchStreet will generally put you in contact with two things: dogs and live music. Of the former, most areleashed and owned. Of the latter, most is free. And because of its free-ness,live music might appear to passersby as a gift from the gods — or maybe the Church Street Marketplace Commission.

 A conversation with Peter Coccoma of Alpenglow, who played for last Wednesday night’s Let It Rain Concert Series, offers an earthlyperspective.

 The five-piece folk-rock band took the stageonly 10 days after completing a monthlong tour.

 “We went from Portland, Maine, to North Carolina andeverywhere in between,” said Coccoma. “We played 22 shows in 30 days.”

Theyreturned to their Burlington base in good spirits, a condition that defied the preemptive warnings of fellow musicians.
