OSU percussionist Bob Brudvig is leading a five-person ensemble in a practice session on the second floor of historic Benton Hall. It may be winter in Corvallis, but the music makes you forget the drizzle outside. It evokes palm trees, Caribbean sun and pre-Lenten carnivals. Brudvig works the melody on his chrome-plated steel drum, tapping out notes in rapid succession to an arrangement of "Gimme de Ting" by Trinidadian calypso legend Lord Kitchener. The group sometimes known as Dr. Bob’s Steel Drum Extravaganza, according to Sam Kincaid, band member and recording specialist in the OSU music department, has been bringing its energetic sound to Willamette Valley performance stages, weddings and other events for the past two years. Its repertoire emphasizes calypso and soca (an up-tempo dance form developed from calypso), traditions from Trinidad where its signature instrument, the steel drum or pan, was born.
