I found the artist I saw on YouTube, Jiri Slavik, the above video links seem to have similar technique. Thanks for the feedback. This is my second attempt at responding to your comments and links, so I'll try again. I am a real novice double bass player. I have owned my bass for just over a year. I am familiar with bowing, I have had several cellos and I play the fiddle. Recently I took my bass to a jam for the first time, there were two guitar players, a harmonica player, and another bass player, using a 5 string guitar bass, and me with the double bass. I used my bow 90% of the time which turned out to be the right move, I could play some really easy but effective slow and simple bowings which added some really interesting fills. Lots of tunes in minor keys, this was a great learning experience for me too! Just by accident the next day I came across the video of Jiri Slavik but only saw enough of the video to get the idea that the bass has lots of harmonic possibilities, I've been experimenting these few days locating some harmonics. Been having fun, hope to join the jam again soon. The power of the bow is impressive, I just ordered a quiver to make the move between plucking and bowing smother. Thanks again.
