For this week's #PrivateJam, we finally take our turn to share. Cool Hunting founder Josh Rubin (whose eternal jam is likely Shuggie Otis' "Inspiration Information") tells us he's recently become smitten with the London-based five-piece Mamas Gun. "Summer always includes lots of time in the car driving with the windows down and music blaring. I usually have a favorite song, or sometimes even a favorite album, on repeat. This summer has been sadly lacking an anthem—until now. 'Red Cassette' by Mamas Gun is fun, a little funky and easily listened to over and over. Thanks to our new friend Larry Flick for the tip."
