In early 1999, Higher Octave Music looked back on its NAC output of the '90s with Higher Octave Is...Smooth Grooves. Because Higher Octave has focused heavily on NAC music and new age, jazz's hardcore has tended to dismiss the label as nothing more than a shameless provider of brain-dead muzak. But instead of generalizing, it's best to take Higher Octave's output on a case-by-case basis. This compilation, which tends to favor the more acid jazz-minded NAC music, demonstrates that Higher Octave's output has ranged from the decent to the forgettable and the mediocre. The CD's more substantial offerings include guitarist Brian Hughes' "Soul Fruit" (a soul-jazz number recalling the organ combos of the '60s), violinist Doug Cameron's lilting "Rendezvous" and guitarist Grant Geissman's funky "Did I Save?" which came from Geissman's In with the Out Crowd -- a CD that had more than its share of flaws but was nonetheless an improvement over the unlistenable, soulless stinkers he'd been coming out with. Unfortunately, tunes by Bryan Savage, Craig Chaquico and others suffer from the same problems -- excessive producing, stiff arrangements and a lack of spontaneity. The best pop-jazz has favored improvisation, and improvisation is something that too many of Higher Octave's artists have avoided in the hope of appealing to NAC radio. This is a collection that has its moments but could have been much better.
