In 2003 Steve began touring and recording with multiple Grammy winners and Atlantic recording artists, The Manhattan Transfer. He remains the first call drummer for The Manhattan Transfer, and works with them as his schedule permits. He is the first touring drummer in the history of the band to actually record with them. He is featured on 3 album releases and 1 live concert DVD. In late 2003, Hass released a solo album named "Traveler". The C.D displays Hass' skills as a talented producer. His usage of sonic layering and drum loops is reminiscent of Jon Brion.
