Mary Louise Parker, Colin Powell, Robert Duvall, Garrison Keillor, and Sandra Day O’'Connor are among the personalities lending their voices to "“The Big Read,”" a new series on XM Satellite Radio created by the National Endowment for the Arts (NEA), XM, and Audible.

"The Big Read" will air 30-minute installments of classic novels, such as Fahrenheit 451 and The Great Gatsby. The show will also feature NEA-produced specials with authors, actors, and other luminaries talking about –- and reading from -– the featured book.

The show will air every weekday starting September 10th on Sonic Theater (ch 163), which is devoted to audio recordings of books and plays.

“"The Big Read"” takes it name from the NEA’s national reading initiative equally entitled The Big Read, which encourages communities to come together to read and discuss a single book.

Other participants in "“The Big Read”" include Cheech Marin, playwright Edward Albee, and authors Ray Bradbury, Amy Tan, and Tony Hillerman.

Each installment of "The Big Read" will air at 2:30am, 10:30am, and 4:30pm (all times ET) on weekdays.
