Since the 1960's, it's become common for bass players to keep a bow handy, and many became adept users-Jimmy Garrison, Ray Brown, Eddie Gomez, George Mraz, Christian McBride, Michael Moore, and others. BUT-99% of the time, they use it only for long tones that are meant to add dramatic underpinning to an intro, in interlude or an ending. Actual bowed (known as "arco") solos are rare.
The recent birthday of Leroy Elliot "Slam" Stewart (b. 9/21/14) reminded me what a virtuoso bass player can do with a bow and how few such players there have been. In fact, I can count them on three fingers, Slam Stewart, Major Holley and Paul Chambers.
