Adam is lead singer and founding member of the rock band Counting Crows. Before forming Counting Crows, Adam was lead singer for Bay Area band The Himalayans. He was also involved in another San Francisco based band, Sordid Humor.
In 1997, he began his own record label, E Pluribus Unum. He signed bands Joe 90, Gigolo Aunts and Neilson Hubbard, all of which he took on the road to open for Counting Crows. In 2000, E Pluribus was put to rest when bought out by Interscope who had no interest in the indie bands that Adam had signed.
