Sidran released his first solo record, Leo and the Depleting Moral Legacy
, while he was in college. The album was a collection of songs he had written mostly in high school, including two songs that had already been recorded by Steve Miller. He played many of the instruments and mixed the record; Paul Peterson, Ricky Peterson, and Steve Marker also contributed.
After returning from Spain, Sidran recorded two bilingual solo albums. In 1998 he recorded L. Sid
in Minneapolis with a studio band including Anthony Cox, Gordy Knudtson and Bob Malach. In 2003 he released Bohemia
, an album recorded in Madison and Madrid, and featuring appearances by Spanish artists including Jorge Drexler
, Ana Laan, and Tino di Geraldo, and American collaborators including Freedy Johnston, Holly Brook, and Howard Levy.
Sidran's fourth solo record, Mucho Leo
, was scheduled for release in October 2014.
During the process of recording Bohemia
, Sidran became friendly with Jorge Drexler and Ana Laan, and would eventually go on to produce and perform regularly with both. He co-produced Laan's Oregano
and Chocolate and Roses' albums, as well as Drexler's Oscar-winning song, "Al Otro Lado Del Rio".
In 2003 Sidran started Nardis Records with his father. The name "Nardis" comes from a Miles Davis composition, but is also Sidran's name spelled backwards. The label was set up as a vehicle to release projects by both father and son, and both have released their recent solo projects as well as other artist productions on the label.
A chance encounter at a jam session in Madison with singer-songwriter Joy Dragland would ultimately lead to the creation of Joy and the Boy; primarily a studio project, the duo released three albums. Their cover of Marvin Gaye's "Let's Get It On" debuted in the Top 40 pop radio charts in Spain.
After moving to New York in 2005, Sidran developed his career as a composer for film and television commercials. He has scored over 100 national television commercials, and six feature-length documentaries including
At The Death House Door and
No Crossover: The Trial of Allen Iverson, directed by Steve James.
