Revelator is a dramatic leap forward for both Susan Tedeschi and Derek Trucks in every respect, from the songwriting and the production to Tedeschi's vocals and Trucks' guitar playing. Their new 11-piece band is an aggregation of talented musicians related by experience, and blood, and clearly adds to the notion of Revelator as a true group album. 　　 　　Tedeschi and Trucks co-wrote the album's 11 tracks with an impressive list of songwriters including: Jeff Trott, John Leventhal, David Ryan Harris and Sonya Kitchell, Gary Louris (The Jayhawks), Oliver Wood (Wood Brothers), Doyle Bramhall II, Erick Krasno (Soulive), Mike Mattison, Kofi Burbridge and Oteil Burbridge. 　　 　　In addition to Tedeschi and Trucks, Revelator features bassist Oteil Burbridge (Allman Brothers) and keyboardist/flutist Kofi Burbridge (The Derek Trucks Band), drummers J.J. Johnson and Tyler Greenwell, trumpeter Maurice Brown, tenor saxophonist Kebbi Williams, trombonist Saunders Sermons and harmony singers Mark Rivers and Mike Mattision.
