For a recent uni project I had to research a performance group of some kind, and then design a poster to advertise the group. My chosen group was The Driftwood Citizens - a jazz/soul/funk band from Boston who were in the middle a UK tour at the time. I went to see them at the Green Man pub in Barnet, and made plenty of sketches while I was there.
Quick, stylized watercolour painting of Dan Gilman - saxophone-player of the Citizens.
