At a glance, Kansas girl Piney Gir, here to play the last-ever Spitz Festival of Country, could hardly look more the part. All beaming smiles, fishnet stockings and billowing baby-doll skirts, she looks every inch the rootin'-tootin' hoedown princess. But not long ago Piney was better known for her synthy bossa-nova pop. The Country Roadshow came into being almost by accident, but has spawned an album and a new set of fans.

The fact that the crowd is somewhat under-capacity tonight only adds to the atmosphere. The candlelit tables down the front add a hint of the burlesque, and the extra elbow room allows for a little bit of a floor show at one point when a couple of old gents get up for a line-dance, looking like Nashville-style Pearly Kings. Even if the band aren't country born and bred, they whip up a perfectly presentable, chiming sound, pedal steel keening and banjo twanging in all the right places. Still, there are moments when it veers towards the middle of the road, and some of the slower-paced numbers mid-set don't have a lot of sparkle.

As she gets into her stride, however, Piney regales us with some blackly funny anecdotes - such as the one about her pet chicken ending up in grandma's soup - and brings out some great tunes, with new single Greetings Salutations Goodbye a clear highlight.

When it comes to the encore, there's only time for one more, and Piney wants to know if we want to hear a mean one or a nice one to finish. "Mean!" comes the unanimous reply, and she duly obliges. It's a great little show Piney's got, but it wouldn't do to be too polite about it.
