I really enjoy Invitation To Openness. Other albums I find comparable for some reason are Larry Coryell Barefoot Boy, Pat Martino/Gil Goldstein We'll Be Together Again, Rahsaan Roland Kirk Case Of The Three Sided Dream In Audio Color, and Yusef Lateef Suite 16 and Part Of The Search. Although they don't have similar sounds and have recognizably separate tracks, they're all an "album experience" with a theme imposed over the duration. They're fun to throw on and listen to entire.
Layers is fascinating from an electronic music perspective (ei. Raymond Scott). It's a bit like Jan Hammer's The First Seven Days, but with a more hip hop-prescient drum sense.
