With all the clubs for jammers in Portland, Oregon, I think Duff’s has always been a bit more Upscale in patrons and talent. They have regular concerts with touring musicians that are prominent in their genre and being such a quaint place, you always have the opportunity to meet them famous folk after the show. There are various kinds of jams, like a separate ‘HARMONICA ONLY’ open mic harp party with a well know Harp player Arthur Moore! Then there is the Root’s Jam, a mix of Blues/Jazz/Rock with a house band backing you! I have even played a bit of funk there! They recently re-located to this new location on 82nd Ave. so be sure to check you have the right address! I give a Thumbs up to Duff’s and I say make this one of your stops while JamTrotting in PDX!
