Originally a native of Dayton, Ohio, Steve moved to Los Angeles in ’94 to expand his musical opportunities. He soon found himself a first call keyboardist on the L.A. scene and began touring the world and co-writing songs with drummer Dave Weckl. Steve then became widely known for his work with Steve ‘Luke’ Lukather (Toto) on the albums ‘El Grupo’, ‘Ever Changing Times’, ‘Alls Well That Ends Well’ and ‘Transition’.
2006 brought about Steve’s highly anticipated solo project, ‘Dark Blue Dream’. It was received with great critical acclaim. His next project ‘Dialogue’, and its successor 'Observatory" were co‐written with his wife, bassist & vocalist, Renee Jones and co‐produced by drummer, Simon Phillips. In 2013 the successful musical relationship between Weingart & Phillips resulted in the formation of the group, ‘Protocol II’. The group is currently touring in support of their CD, ‘Protocol II’.
