Regina Carter (b. 1966) heralds the return of the violin to [mainstreamjazz. Since the passing of Stephane Grappelli the violin hasn't had a definite presence in jazz. (Jean-Luc Ponty, who always leaned toward rock/jazz fusion offered some contribution outside the mainstream.)

Carter, who hails from Detroit, Michigan, began a career with the band Straight Ahead after graduating from the New England Conservatory. She then played with the Uptown String Quartet and Max Roach, the patriarch of jazz percussion . Although her first albums were R&B oriented, she dove into in the jazz mainstream playing with Wynton Marsalis in Blood on the Fields. She has also appeared on albums by Tom Harrell, Cassandra Wilson, Kenny Barron, and Steve Turré.

I don't yet have confirmation, but I am pretty sure that the saxophone-wonder James Carter is her brother.
