Bound Stems are severely awesome. I got into them through their last album, Appreciation Night (2006), and especially the killer track "Wake Up, Ma and Pa Are Gone".
Their new album, The Family Afloat is really, really good. Highly recommended. Given that Amazon hasn't got their shit together for MP3 downloads yet*, your best bet to get your hands on a copy is emusic.com.
*: I hate regional lockout. It costs them no more to deliver an MP3 to New Zealand than it does to send it anywhere else in the world. The only reason they do it so that they can keep reaming us with $35 CDs.
