Being a classical musician I'm no expert on the popular scene in Dublin. However, certain venues, particularly pubs, host gigs and especially at weekends. Beware of expensive covers and crowded venues though. The best up to the minute guide may be found on Aertel p370 - most of the venues tend to be pubs and clubs.
The Hot House Bigband play every Monday night at The Mercantile Bar & Grill Dame St Dublin Doors open at 9pm and admission is €8 euros.
Dublin audiences are really lively and you might enjoy combining a visit with a concert or gig.
