Spacey piano work from Jordan De La Sierra – material that's clearly informed by the 60s experiments of La Monte Young and Terry Riley, but which also has a more open, spiritual quality too! The piano has a nice sense of tuning – one that's almost watery at points – and Jordan's in no rush to let the notes unfold, as he often waits for one to resonate out before starting the next – which creates this very spacious, meditative quality throughout – a mode that's also inspired by Indian music, but much more laidbck and North California! The package reproduces the original 2LP set – complete with artwork and original notes. CD

A pivotal album from minimalist genius Steve Reich – a record that got him into living rooms across America – thanks to the album's higher concept, and key participation of the Kronos Quartet and guitarist Pat Metheny! Kronos perform on the long title track "Different Trains" – a piece that is both a meditation on train travel and its role in the Holocaust – performed by the quartet with additional sounds from Reich on tape! Metheny's guitar sounds fantastic on "Electric Counterpoint" – a work that's completely faithful to the amazing range of tones and colors he'd been bringing to his own albums for years, but which also reworks things with Reich's minimal modes.

The sound of silence, taken to a new level – as John Cage works beautifully here in an illustrative piece inspired by a rock garden in Kyoto! There's a very spacious quality to the piece – instrumentation that really leaves lots of space in between the notes – even though the piece is performed by a sextet that includes Eberhard Blum on flute, Ivewn Hausmann on trombone, Robert Black on bass, Gudrun Reschke on oboe, John Patrick Thomas on voice, and Jan Williams on percussion. The hour-long work builds beautifully – and has this evocative, Eastern-styled vibe that definitely lives up to its inspiration! CD

The compositions of Cornelius Cardew, performed here with a distinctly Chicago inflection – in a relatively recent performance that is partially conducted by Art Lange, and featuring Jim Baker on Arp, Carrio Biolo on vibes, Jeb Bishop on trombone, Fred Lonberg-Holm on cello, and Jeff Parker on guitar. Given the relation of some of the players to Lonberg-Holm's Lightbox Orchestra, there's definitely a similar feel here – a sense of timing and interplay that illuminates Cardew's compositions nicely, in the hands of musicians who can understand the complexities of his work, and make the best of the freedoms he allows them. Titles include "Autumn 60", "Treatise", "Memories Of You", "Material", and "Octet 61 For Jasper Johns". CD

An amazing record, and one that forever transformed the sound of opera in the US – the amazing summation of all the many musical ideas that Philip Glass had been cooking up since the 60s, done as a mindblowing stage presentation with Robert Wilson! Voices, organ, reeds, and piano come together in wonderful lines that go on and on, seemingly forever, in endless variations and rivulets of sound – as simple in structure as the leaner small combo minimalist work from Glass – but with a very different style in the fuller setting, with a sonic quality that still is as groundbreaking today as it was back in the 70s!
