Has it really been 20 years since Lisa Loeb’s breakout hit single, “Stay (I Missed You)” went platinum? In the two decades since Loeb was introduced to the world, with her defining eyewear and lithe voice, the songwriter has continued to produce quality pop music and has also recently dabbled in children’s music and other media projects. Last year, Loeb returned to the world of pop music with her album No Fairy Tale. Glasses still frame her youthful face, and emotionally poignant lyrics still populate her songs, and this week Lisa Loeb brings her extensive with her when she performs on Sunday, Sept. 7, at Sweetwater Music Hall, 19 Corte Madera Ave., Mill Valley. 8pm. $27—$32. 415.388.3850.
