A brass ensemble might not be the first thing you’d consider when searching out world music, but the Westwind Brass, who performed at the Neurosciences Institute on Apri 18, is much more than just a traditional horn quintet. An ensemble-in-residence at San Diego State University, the group includes Dave Pollock (trombone), Andrew Elstob-(trumpet), John Wilds (trumpet) Barry Toombs (horn) and artistic director Brent Dutton (tuba). The performance, “And the World Resounds,” invited listeners to do a bit of aural globetrotting. “The music is from all over the world and different historical times too,” Dutton said. “When I do the verbal program notes from the stage, I tell people it’s kind of like you’re taking a cruise, first class of course, around the world and you’re sampling the musical cultures of many different places.” The Westwind Brass was founded in 1986 as a student chamber group, with Dutton as coach. When the members graduated, they decided to expand into a professional brass quintet. While the group is successful today, with world tours and six albums to their credit, the original prognosis for the project was not good. “Of the people who form groups like that, usually one in about a hundred succeed,” Dutton said. The group has instituted several educational programs, performing at area schools frequently through the year. “I think that to be able to play music live for [kids] and have them be able to ask questions and interact is incredibly valuable,” he said.
