There's more to Memphis than Graceland — a fact that LA-based writers Melissa and Justin Gage tackle in their recent collaboration Memphis and the Mississippi Delta: A Complete Guide. Tonight, the two read from and sign their singular city guide, which explains why it's more important than ever to keep the Delta blues tradition alive. Melissa, a freelance writer and screenwriter, contributes weighty travel-writing expertise, while hubby Justin brings music knowledge to the project, having founded Autumn Tone Records and music blog Aquarium Drunkard. Stick around after the signing for a party in celebration of the book — and the cultural heritage of the birthplace of the blues.
