Songwriter Iain Matthews’ wandering spirit has made him an influential artist over decades in a wide array of genres. Matthews first foray into music was as a founding member of English folk band Fairport Convention in the late 1960s; after a few years, Matthews left the band and founded Southern Comfort. This trend continued for decades, as Matthews continuously sought new avenues for making music, mastering genres from jazz to country along the way. Matthews is a selective performer, so it’s a treat for the North Bay that he’s playing a special acoustic show alongside equally influential French-born songwriter Clara Bellino on Tuesday, Nov. 17, at Fenix, 919 Fourth St., San Rafael. 7pm. $15. 415.813.5600.
