Join a bunch of musos doing their thing - solos, groups, bands and a good old jam later. Mostly blues, a little jazz, some good old rock. Starts 7ish.
A wee drinks discount if you play. Sound system, keyboard and drum kit provided - bring your own guitar, bass, voice, trumpet - whatever.
Double Bass most appreciated. If this achieves a modicum of success, we may be able to repeat it - last Wednesday of every month. Tell your mates.
