Rhythmic Designs expands on the groundbreaking polyrhythmic, polymetric concepts covered in Harrison's previously published Rhythmic Illusions, Rhythmic Visions and Rhythmic Horizons books and videos by offering detailed analysis and transcriptions of twenty drum tracks from the recent Gavin Harrison & 05Ric albums Drop and Circles (featuring guitarist Robert Fripp and keyboardists Dave Stewart and Gary Sanctuary). Along with the 204-page book of note-for-note transcriptions and practice exercises, the double-sided companion DVD features more than two-and-a-half hours of video packed with descriptions and discussions of the drum parts, set-ups, tuning and recording process - plus six minus-drums, play-along tracks.
