It is more than fair to say that In C (1964), a repetitive composition of unpredictable length by California native Terry Riley (b. 1935), forever changed the course of modern music. If you want to have a fabulous time learning why, listen to In C on Four Four Three: The Music of Terry Riley. The new DSD-native recording from Channel Classics by the Ragazze String Quartet, percussion quartet Slagwerk Den Haag, and genre-redefining drumkit/French horn/guitar trio Kapok, can be purchased in either CD format or as a stereo or multichannel download in resolutions up to Quad DSD. This collective achievement is so superbly recorded by Jared Sacks, and so colorful, that it will likely send your head spinning into another dimension.

The vinyl LP shopping in Amsterdam is as good as anywhere I’ve ever been outside Greenpoint, Brooklyn.

"The days grow short when you reach September," sang Frank Sinatra and Tony Bennett, but not so short that you won't have time to enjoy our September issue, which hits newsstands, mailboxes, and tablets this week. Technologies vintage and modern are featured, with Ken Micallef's review of the Music Hall MMF-7.3 turntable and Jim Austin's interview and MQA's Spencer Chrislu taking pride of place on the cover. And there is more on MQA inside, with John Atkinson writing about his listening comparisons between MQA-encoded files and the hi-rez PCM originals.

This is easily the best thing any of the three have done in many years.
