Just finished listening to the Bartz Bremen set. It's wonderful. First off, sound quality is outstanding for a 70's live recording. Musically, it's an extension of what he was doing on the "I've Known Rivers" Montreux set. This is two years later, and Charles Mims and Curtis Robertson have replaced Hubert Eaves and Stafford James. Robertson is outstanding, and very well miked/mixed. It is an active joy to listen to hs bass work here. Mims also does a good job. This set is 50% longer than the Montreux set, equivalent to three LP's, and every cut works ("Rivers" had a couple of throways). Even the Isley Brothers cover is lovely, excellent work by Bartz and Robertson especially. "Rivers" was my previous go-to Bartz album, so this will be my new one, though I love much of his catalog. This is different enough in both content and execution from the Montreux set that if you like that, you'll definitely also want this one. And the success of this release makes me ready to go check out the Airto/Flora release.
