Jason Mraz

After releasing “Love Is a Four-Letter Word” in 2012, San Diego acoustic strummer Jason Mraz has opted for one-word album titles. There was “Yes!” in 2014 and now “Know” this month. Clearly his recent stint on Broadway in the Sara Bareilles-penned musical “Waitress” didn’t impact his music. The feel-good singer-songwriter is still offering lightweight pop in an easy-listening style that fits in with his ’00s radio favorites “I’m Yours” and “Lucky.” Brett Dennen opens.
