Bonham and the Strangers:

Although it has been seven years since her song ''Mother Mother" was nominated for a Grammy, former Boston rocker Tracy Bonham has kept busy with a slew of projects, from performing on the Blue Man Group tour to joining the Wayfaring Strangers, whom she'll be with tomorrow at the Somerville Theatre after doing an opening solo set.

''I've played with them off and on in the last few years," she says of the Strangers. ''I love their range of music, from jazz and gospel to bluegrass and sometimes klezmer. And what I try to add is the gospel. It's a chance for me to sing old Mahalia Jackson and Staples Singers songs."

Bonham was brought into the Strangers fold by Matt Glaser, who also works in the string department at Berklee College of Music, where Bonham met him in the late '80s when she studied there. ''Matt is also the guy who got me the gig with Page & Plant," she recalls of the '90s tour for which she played violin.

Bonham also just completed her first album for Cambridge's Rounder Records. It will come out next year and feature such guests as Sebastian Steinberg on upright bass, Mitchell Froom on piano, and Dave Levita on guitar (he tours with Alanis Morissette). ''It's more of a pop-rock album, but I can't wait for people to hear it," she says.
