Two authors with ties to Kansas University will read from their latest respective projects. KU professor of English Iain Ellis is the author of “Rebels Wit Attitude: Subversive Rock Humorists,” which pays tribute “to the great rebel humorists in American rock history (by) investigating comedy and laughter as the catalyst and main expressive force in these artists’ work.” Daniel A. Hoyt, who received his Ph.D. at KU, recently released the short story collection “Then We Saw the Flames,” which won the 2008 Juniper Prize for Fiction. As part of their Ad Libri Per Aspera tour, Ellis and Hoyt will read from their books (and Ellis will play a few tunes) at 7 p.m. today at The Raven Book Store, 6 E. Seventh St.
