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.
But I don't know if people are meant to be together. You have to have a lot in common, choose well and be really fortunate. It's not like you're sprinkled with fairy dust. You have to believe that love will be there when you need it.
