This month’s Portland FolkSong concert features Cabin Fever NW, on Friday, May 18, 7:30 pm, at the Reedwood Friends Church, 2910 SE Steele St.

What began as an adventure by two best friends, the group has grown into a performing quintet that now includes Dianne Bochsler (vocals, rhythm guitar) and Tara Caldwell (vocals, clawhammer banjo) of Bellingham, WA, Ed Johnson (vocals, lead guitar), Cary Black (vocals, bass fiddle), and Paul Elliott (fiddle). It’s music from the heart, with fine songwriting and four part harmonies.

Their most recent album is called This Night That Lasted Days. Tickets are $20 GA, $17 PFS, $10 youth available in advance at portlandfolkmusic.org/concerts.php. See cabinfevernw.com.
