I've no idea how things work in New York but one of the answers in the UK to 'how do I get more paid work for my band?' is the Irish Pub Scene. These 'theme pubs' are still popping up all over the world (there's a thread about one in Tokyo), and they tend to offer live music opportunities. I'm sure you and your band are familiar with this kind of work, but I am kind of curious to know how it operates in New York with so many of the population having Irish ancestors.
The Downside. In the UK at least there is a certain repertoire that 'must be performed' - The Wild Rover, the Irish Rover, the Auld Triangle, Dirty Old Town, Fiddlers' Green (not all Irish songs as you can see!). But I know a few people (and some excellent, well-renowned musicians among them) who do or have done this sort of work as it helps to pay the bills and allows them to keep playing. Perhaps New Yorkers are more (or even less) discerning?
