Sick Boys Club from Birmingham, Britain (UK) are fit in many styles. Burlesque musictheatre, mineworkers shuffle, nutty sound ska,... very interesting, because the music is full of ideas. You cannot categorize them or thro them into a genre-box. The only box would be labeled with "miscellanous". No charts-music, but experimental underground. They work without synthesizers, all natural instruments - or good emulated by software.
