Gerd graces us with an ostensibly insider concept that works for the masses. Gerd. Modified is a compilation of Gerd remixes, other artists remixing Gerd, and Gerd remixing themselves. All Gerd all the time works, though. The beauty of Modified lies in the imaginative inclusion of throwback instruments such as flute and flugelhorn, accenting the sensuous melodies sliding through virtually every track. Vocals are given special attention here, to especially good effect with Alissa Kuecker on “Shine,” as well as the Brasilia-tinged “Tesao.” “Onkel Joe,” a ’70s German jazz classic, undergoes a Latin makeover with a bit of 5/4 beat thrown in-just one of the tricks in the Gerd arsenal.
