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

Classic recording of Crumb's "Black Angels", performed by the electricized New York String Quartet, featuring Paul Zukofsky. Zukofsky also performs on the other two pieces, composed by Charles Jones. LP, Vinyl record album

Maybe one of the coolest volumes ever in this long-running series from John Zorn – but maybe that's also because the album's dedicated to the great Terry Riley, and features Zorn improvising on organ, on two long tracks that definitely echo the minimalist legacy in Riley's music! The organ is a pipe organ, which has a much fuller sound and larger presence than some of the electric keyboards that Riley used in the past – and while Zorn echoes that sense of song progression that you'll know from the composer/performer's famous recordings, he also lets loose with his own sonic tendencies too – and explores some of the farther reaches of the pipes with very heavy sounds! The album features two long tracks – "A New Door Opens" and "Elissa's Tears" – both improvised. (Jazz, Out Sound) CD

To most ears, trumpeter Jon Hassell first burst on to the world through his experiments with Brian Eno on EG Records, or maybe his 80s work on ECM – but here, on his debut for the small avant label Lovely Music, it's clear that Jon's already in complete control of his sound – and is ready to become the kind of performer that would captivate listeners for decades to come! Hassell's horn has that special sort of effect quality on most numbers here – spacey, but never slick – and electrified, but far from any sort of Miles Davis mode – especially considering that the music is full of earthy, organic percussion from Nana Vasconcelos and some other players, who balance out the set's work on Fender Rhodes, Arp, and Serge synthesizer. The spirit of the set is very much in Hassell's classic "fourth world" recordings – and titles include "Toucan Ocean", "Hex", "Blues Nile", "Vernal Equinox", and "Caracas Night September 11, 1975".

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

The final album in the "qatsi" trilogy, and one that's got the same sublime Philip Glass scoring as the others – but which also features some beautiful cello solos from Yo Yo Ma too! Given that there's a darker side to this film, the warmth of the cello balances things out nicely – and occasionally creates a nice juxtaposition with a few of the more urgent moments in the larger orchestrations – which are performed by the Philip Glass ensemble. Titles include "Media Weather", "Old World", "Intensive Time", "Primacy Of Number", "The Vivid Unknown", "Point Blank", and "Definition". LP, Vinyl record album
