Personally, I've found one of the more stimulating ways of playing in recent times has been to kind of move outside the free improvised area and work with people who are probably improvisers but they have a particular way of working.
I think I'm more influenced, just in general, not by blues artists, but more by stuff from Curtis Mayfield, Stevie Wonder. Stevie Wonder is probably my biggest musical influence of all. And Donny Hathaway.
