Eric Preston Suan, a graduate of Gilman School and a sophomore at Dartmouth College, said he loves to sing but is majoring in engineering and considers singing more of a hobby.

But Suan, a baritone, who goes by his middle name, is in the hunt for a recording contract and $200,000 as a member of the singing group the Dartmouth Aires, which is competing for the top prize on the NBC-TV show "The Sing-off."

The a capella group sang for the first time this week and is competing weekly in the elimination contest, which was mostly taped this summer at a studio in Culver City, Calif.

Only the finalists will compete live in November. The show airs Mondays at 8 p.m.
