On Saturday night, Seattle indie rockers Mt. St. Helens Vietnam Band captured a rare piece of rock history by becoming the first band in the continental U.S. to ever play on an active volcano. The fact that the quintet played the volcano in which they take their name, Washington State's Mt. St. Helens, made the performance even more unusual as they treated fans/hikers/mountaineers/park rangers to an hour-long set of brand new tracks and favorites from their self-titled debut. So how does a band get to play such a dramatic venue? Well, after the folks at the Mt. St. Helens Institute learned of the five-piece band several months ago, they asked them to play a benefit show at the volcano which famously erupted on May 18, 1980. The band graciously accepted and on Saturday night they dove into one lava-hot set. But first you have to get there -- and that's a journey in itself.
