With his fourth album, Berlin-based Richter further cements his status as one of the leading lights of modern composition. Each of this album's twenty-four tracks is a classically-composed ringtone, an evocative miniature whose theme, though fully developed, hints at a larger piece; thus Richter explores the fugitive nature of memory through reprises and repetition throughout this intriguing album. With a sonic palette consisting of string quintet, solo piano, 16-track 2-inch tape, transistors, found shortwave radio, vinyl clicks, dust, scratches and rumble, and acoustic guitars, Richter's latest effort is both beautifully detailed and sonically rich.
