Christian Weidner's alto saxophone flies over the piano/bass/drums rhythm section of his groundbreaking quartet on 'Every Hour of the Light and Dark' (Pirouet Records). It's a heady concoction whose circuitous road is so delicious that while the destination remains unknown, it's the getting there that's all the fun.
For his 16th CD, Henning Sieverts' 'Double Quartet' (Pirouet) reaches back over 600 years to research the history of the Bavarian Irsee Monastery in uncovering a mass written in 1614. He then wrote 15 original pieces of music (shortest 51 seconds; longest 12 minutes) for duo, quartet and octet in a similar style but expanding it into modern jazz. No overdubs.
