Mary Halvorson has long had the reputation of being among the most inventive guitar stylists in avantjazz, but here she teams up with longstanding pal, multi-instrumentalist Robbie Lee, for a suite of improvised vignettes that are much more difficult to define. The whole date rests on the gimmick of the two of them playing highly unusual instruments – Halvorson's from the guitar family, Lee's wind instruments – and, in fact, it was the first time Halvorson had ever touched some of them. As such, there's an irrepressible freshness and sense of real-time discovery here, and more than a little humour too. Lee blows a growling, humming melodica, Halvorson responds with bluesy curls from the Gibson guitar. Halvorson rumbles the low end of the Knutsen harp guitar, Lee trills a medieval sounding chalumeau. Or the two of them engage in a hilariously uptight little dialogue of miniature whinnies on the soprillo – the world's smallest saxophone – and stunted banjo pizzicato. This is bags of fun.
