On the first Thursday of every month, the Peter Brown Quartet plays mainstream jazz to a packed and enthusiastic crowd at the Queen's Hotel in Carleton Place, 142 Bridge Street from 6 to 9 pm. The band is four of the most acclaimed jazz musicians in the Ottawa Valley: Don Paterson, trumpet and vocals; Glenn Robb, drums; Dave Arthur, bass and vocals; and Peter Brown, piano and vocals. There are always a few accomplished sitters-in, usually for a last-set jam.
