Eight Gigs: Tango Alpha Tango

Portland trio Tango Alpha Tango has the down-and-dirty of blues-rock covered, particularly with its older material. Guitarist and frontman Nathan Trueb brings a haunting, passionate voice to the music that is equal parts Robert Plant and Portugal. The Man’s John Baldwin Gourley. However, the new album, White Sugar, moves the away slightly from familiar blues-rock territory; it’s an eerie, moody indie-rock record that still delivers on the rocking-out front, but with a lot more restraint and more unusual choices of chords and structure. 1517 21st Street, www.tangoalphatango.com.
