Russo began his career as a musician at the age of 18 by joining his older brother's band Hopewell, which focused mainly on psychedelic rock balladry and lengthy "shoegazing" soundscapes.  After releasing their first record "Contact" on Burnt Hair Records, both brothers took a break from their own project and joined indie/experimental band Mercury Rev.

David Baker (singer): David Baker is the former lead singer and founding member of the band Mercury Rev.  He is prevalent on the albums "Yerself Is Steam" and "Boces" and all of the singles and Peel Sessions the band did concurrently.  Mercury Rev's sound changed considerably after the departure of Baker, whose deep voice was replaced by the much higher-pitched singing of Jonathan Donahue.

Comet (band): Comet is an American indie rock band that was formed in 1993 in the Dallas, Texas suburb of Mesquite.  Described as an enigmatic noise pop outfit brought together by a common love of the Beatles, the original lineup of singer/guitarist Jim Stone, his bassist-brother Neil Stone, guitarist Daniel Huffman, and percussionist Josh Garza entered the studio later that year to cut their debut single "Portrait," produced by Mercury Rev alum David Baker.  A deal with the Arista subsidiary Dedicated label followed, they became label mates with Spiritualized, Beth Orton and the Cranes and with Baker again at the helm, Comet recorded their LP bow "Chandelier Musings", issued in late 1996.  The band toured throughout much of 1995 and 1996 and into early 1997 when fallout from a tour-van accident led to the eventual break up of the original line-up.
