As one of the starts around the world for nightlife Bangkok boast a vast range of Live Music Venues, from simple jazz to full orchestras with associated entertainment.
Most venues have a relatively ‘democratic’ pricing policy. Many feature beer towers(excellent as it keeps the beer cool and you just help yourself when you want more).
Bands from abroad and also from Thailand(be sure to try to hear the amazing Isaan Rock is you have a chance) and all generally perform extremely well, playing with a passion. The bands are generally universal and as happy to play Pink Floyd as they are to play local music.
The majority do not charge entrance fees and prices will depend on your tipple.
