About Brass

Drew Mazurek, trumpet

Photo by Marilyn Catasus Drew Mazurek co-founded Brass in the Spring of 1999, while still an undergraduate at Yale University. He performed with the group for seven seasons before leaving in 2006 to pursue graduate work in Electrical Engineering at Stanford. The trumpet called him back in 2008, and he's been a full-time member ever since. His personality and musicality are an integral part of the sound of Brass.

A native of North Haven, Drew has studied with Richard Green and Ken Tedeschi. He has performed extensively with groups at Yale and Stanford — including the Yale Concert Band, the Yale Precision Marching Band, and the Stanford Wind Ensemble — as well as the Connecticut Choral Society, the Wallingford Symphony Orchestra, Orchestra New England, the Guilford Town Band, and in dozens of musical theater productions. He has performed in nine countries spanning four continents and holds degrees from Yale (BS) and Stanford (MS).

When he's not playing trumpet, Drew can usually be found flying airplanes over the Connecticut coastline or building things at Veoci, his New Haven-based company. A native of North Haven, he now calls New Haven home.
