It's Gaelic meets Gallic on post-weekend North Avenue. You'd expect an Irish bar to get its fiddle on with a trad-music night, and Liam's beats the bodhran each Wednesday for a real good time. But on Monday evenings, this working-man's Celtic drinkery swaps jigs for gypsy jazz and transports patrons to a throwback Parisian nightclub with Django Reinhardt manouche jazz sessions. From 8 until 11, it's all about celebrating the jumping, acoustic guitar-driven jazz stylings Reinhardt birthed in the 1930s and '40s (despite his having only two fingers to work the fret board). As at a true jam session, you never know what musicians will turn up, though members of the Hot Club of Baltimore, a skilled ensemble specializing in Django ditties, are regulars. We've also heard clarinetists, bassists, vocalists, and even someone taking on the role of violinist Stéphane Grappelli (albeit on a light-up, clear-plastic instrument). Need more enticement to separate butt from sofa on a Monday night? This is the evening when Flynn's serves hand-pumped pints of cask-conditioned ale for $3 each until 8 p.m., and $4 a pint after that.
