If you’ve been at a North Bay fair, festival, club or coffeehouse any time in the last 25 years, you’ve probably heard married musicians Allegra Broughton and Sam Page perform as Solid Air. As a duo or a full band, Solid Air mix Americana melodies and jazz grooves, and the group’s continuing lyrical message of peace and understanding is more resonant than ever. This week, Solid Air unveil their new album, Beautiful World, recorded at Prairie Sun Studios in Cotati and released on Sonoma County label Jackalope Records, and perform on Saturday, July 1, at the Last Record Store, 1899-A Mendocino Ave., Santa Rosa. 2pm. Free. 707.525.1963.
