Blat blat blat

On my way home yesterday there was a group playing in the subway and the best way I can describe it was rude blatty trombones with trumpets, drums, bass, and the whole had a feeling of a great big jiggly lumbering machine rolling forward with an overall beat you wanted to smile and move to.

I've heard this style of music before but I can't summon a nameable song in my head. It's driving me crazy.
