Baraboo, WI natives Phox art-popped their way into my heart a few months back at a small venue in Champaign, IL. In an era plagued by hordes of bland folk-popsters managing to climb their way up the Billboard charts, it’s bands like Phox that make me realize the potential in the folk revival-revival. Phox is, in essence, post-post-folk, with obscure but accessible melodies and rhythms, instrumental and dynamic depth and tasteful (but not overused) harmonies. Phox opens for beloved Portland, OR folk-rockers Blitzen Trapper at the 40 Watt Wednesday. And, though Blitzen Trapper has a few years and records on the opening act, the seven-piece Midwestern musical marvel will certainly hold their own.
