He also had touring stints with artists such as, Richard Bona, Christian McBride, Suzanne Vega, Miri Ben Ari and many more. The Ravi Coltrane group gave Steve his first major label album credit for the critically acclaimed Mad 6, released on Sony Music, as well numerous european tours. At 24 years of age, Hass was touring and recording with some of the world's most influential artists and making a name for himself as an in demand session musician.
