You might know Maria Muldaur for her multi-Grammy-nominated 1974 hit, “Midnight at the Oasis.” In the five decades since, Muldaur has taken her genre-spanning repertoire to stages across the world and recorded a whopping 41 (!) solo albums. Now, she’s narrowed her focus to her favorite genre—the blues—and fans of Americana music are practically obliged to catch her live at the Mount Baker Theatre on March 30. Mount Baker Theatre, 104 N. Commercial St., Bellingham, 360.734.6080, mountbakertheatre.com
