I love lots of different styles. My heart is in rockabilly, very close is proper country/hillbilly/honky tonk/country boogie/western swing/Rock N Roll.
I enjoy bluesy stuff, but more akin to the early raw blues, Muddy Waters, JLH, etc rather than what seems to be referred to as Texas blues.
I enjoy the odd bits of modern stuff, some classical, Motown/stax/northern soul type stuff.
The important bit for me is music must be played like it is meant, and needs to have some form of tune! It'd rather see an averagely competent band that get up, have a ball and put their soul into it, than a polished performance that you know will be identical tomorrow night. An example is Lucas and the dynamos on the rock n roll scene. I've not managed to see them since they reformed, but they were not the most technically capable band, but you were always in for a show.
