A nifty pairing, this. Bush has not only survived, but actually transcended a couple of generations’ worth of bluegrass/newgrass controversy to become a supremely relaxed and confident performer who can jam out on slide mandolin at one moment and belt out a Country Gentlemen classic the next, backed by a band every bit as adventurous and capable as he is. At this point, he’s legitimately called an icon, and he got there the hard way. Williams, on the other hand, is still not quite all the way through the transition from young multi-instrumental virtuoso and sideman to frontman creating his own sound, but he’s already a prodigiously talented musician with a solid band who only lacks a set list of songs that are unmistakably his. In the meanwhile, it’s a pleasure to hear his rich, plaintive baritone voice sing just about anything.
