Mayer Hawthorne teamed up with HUF for a very special closing to his two month long US tour. On April 15 the tour will wrap-up in San Francisco, so Stones Throw has collaborated with the clothing line and designer Freegums for a collaboration pack as well as the above video. The pack features a super dope t-shirt and a Heart-Shaped USB with Mayer's cover of Tony Bennet’s 'I Left My Heart In San Francisco', which can be heard above.
