Portland, Ore. indie outfit the Thermals have gone through significant lineup changes in their eight years together. Vocalist/guitarist Hutch Harris and bassist/multi-instrumentalist Kathy Foster have formed the core of the group while a handful of drummers and guitarists have come and gone. The band rounded out their trio with the addition of Westin Glass -- their fourth drummer -- in 2008, but on their most recent record, 2009's Now We Can See, the band was still working as a duo. On the album's title track, Foster performs all rhythm section duties while Harris takes his usual place as lead vocalist. There may only be two of them, but there's more than enough rambunctious power pop energy between them.
