In honor of the great enigma Sach’s birthday, we are going to Mumford & Sons at the Warfield. They walk that fantastic line of folky rock music that I rarely deign to tell people I enjoy (blaming it on vestiges of my old and abandoned affair with Dave Matthews) but still has a special little place in my heart. So onwards into a night of southern food, mason jars full of cocktails, and a band that includes a banjo in its line-up. Oh and here is a new song from them.
