Leeds had (has?) a thriving jazz scene up until a few years ago. Many of the visiting top acts would have a 'one-nighter' there as part of any European/British tour.
Over the years I've seen Dave Holland, John Scofield, Andrew Hill, Geri Allen, Tomasz Stanko, Ken Vandermark, The Bad Plus and many other playing there. Since all the tours must have been heavily subsidised by the Arts Council, I suspect those days are over!
