It’ll be a David Byrne two-fer in September. Not only will he open his tour with St. Vincent on Sept. 15 at the State Theatre but the night before he’ll promote his other new project, a booked entitled “How Music Works,” with a conversation at McNally Smith College of Music.

The book event is sponsored by 89.3 the Current, whose morning DJ Steve Seel will interview Byrne. Tickets cost $10 to the 7 p.m. session. Books will be available for sale; “How Music Works” will be published Sept. 12. The Current hasn’t announced the on-sale date for tickets.

The book isn’t the only Byrne project arriving that week. His album with St. Vincent album, “Love This Giant,” will be released on Sept. 10.
