Da Vinci's Notebook (or simply DVN) was a comedic a cappella singing group. Richard Hsu and Greg "Storm" Dicostanzo were both founding members of the a cappella group The Generics from the University of Maryland. Formed in 1993 in Arlington, Virginia, USA, the band achieved early success in the a cappella community with their appearance at the 1996 Harmony Sweepstakes finals. They continued to tour, locally and nationally, for the next ten years. Highlights included some of the most prestigious folk venues and festivals on the East Coast, such as Falcon Ridge Folk Festival.
