He is a founder and former lead singer of the singing group Rockapella and a pioneer of the modern A cappella movement. He was a member of Rockapella from its inception in 1986 until he left the group in 1997 to pursue a solo career.

As a founding member of Rockapella, Altman is perhaps best known for his role on the long-running PBS children's geography game show, Where in the World Is Carmen Sandiego?, and where his band served as the house vocal band and comedy troupe. He and his childhood friend David Yazbek co-wrote the show's now-classic theme song and Altman is remembered in particular for his trademark blond braids, which were ceremoniously removed in the last episode of the fifth and final season by the show's host Greg Lee.

As a solo artist, Altman has released three solo albums on Chow Fun Records (seanDEMOnium, alt.mania, Losing Streak); a holiday album with The GrooveBarbers, an A cappella quartet composed of some original Rockapella members and best known for its appearances on national TV commercials for Astelin nasal spray; and an album with What I Like About Jew, a comedic song duo which broke up in early 2006. In December 2006, Altman founded the solo comedy song act JEWMONGOUS and, in 2008, he released that act's debut album Taller Than Jesus, about which The Washington Post wrote "Witty and outrageously lampooning...full of catchy melodies, clever arrangements and lyrics that yield satiric gems." In 2009, Altman wrote and recorded two songs for the popular Schoolhouse Rock series, composed and performed on two TV commercials for Wendy's and composed and recorded the theme song for the PBS show "Science Mission 101" (WQED Pittsburgh).
