Is It an Improvisation?

I actually heard you perform in Wigmore Hall in London night passages. The first half of that concert was sort of a more traditional clarinet recital with Roland the wonderful piano, Roland Pontin, wonderful pianist and then the second half was it felt like an improvisation even though obviously it wasn't but in a sense it felt like everything kind of melted into everything else. And so you've done a lot of work on sort of reimagining concerts in that kind of way. Yeah but I don't think it's totally wrong describe as an improvisation because the bass player he is an improvisator so he could do anything I mean also classical and we have decided in tune but
