Just as the title suggests, this DVD focuses on the advanced topics of independence and polyrhythms, with challenging yet highly educational clips from Gavin Harrison (Porcupine Tree), Steve Smith (Journey, Vital Information), Antonio Sanchez (Pat Metheney), David Garibaldi (Tower of Power), Derek Roddy (extreme metal master), Todd Sucherman (Styx), Randy Black (Annihilator, Primal Fear), Chris Coleman (Chaka Khan, New Kids on the Block), Thomas Lang (Stork, Gianna Nannini), John Riley (jazz legend), and Phil Maturano (Afro-Cuban expert). The program is hosted by Chris Pennie (The Dillinger Escape Plan, Coheed & Cambria), who brings his own expertise on these topics to bear as he introduces each artist. Bonus footage of Chris is also included. Priced affordably and containing a wealth of previously released material from the Hudson Music catalog, the titles in the Ultimate Drum Lessons series have proven to be very popular with drummers. In response to customer comments, the clips on these new releases have been chosen specifically for their educational/instructional content (less concert performances and more actual lessons).
