Anthony Braxton has one of the largest discographies in music history, encompassing a huge variety of styles and formats: operas, pieces for two pianos, orchestras, solo saxophone, 100 tubas, jazz quartets, ‘found’ objects and many more.

The saxophonist/composer/teacher turned 80 in June, and has also just been inducted into the illustrious DownBeat Hall of Fame.

This writer has long championed ‘Forces In Motion’, Graham Lock’s excellent book about Braxton’s November 1985 tour of England, and a large portion of that tour can now be heard on a thrilling digital box set Quartet (England) 1985, for which Lock has provided new liner notes (he also recorded all the material on a portable cassette player).

The quartet, which comprised Braxton on various reed instruments, Marilyn Crispell on piano, Mark Dresser on double bass and Gerry Hemingway on percussion, was one of Braxton’s most active bands in the ’80s, but didn’t record in the studio until 1991.

Quartet (England) 1985 presents four complete concerts from Sheffield, Leicester, Bristol and Southampton (the London concert was officially recorded and broadcast by BBC radio). The original mono cassette recordings, captured by Lock as references for his book, have been restored by engineer Christopher Trent.

The package also features bonus recordings of the quartet playing John Coltrane’s ‘After the Rain’ and Miles Davis’s ‘Four’, plus soundcheck recordings of ‘All The Things You Are’ and ‘On Green Dolphin Street’. There are also previously unseen photos taken during the tour and a full list of the compositions played (the set was different every night).

There’s no getting away from the fact that these are wild and woolly mono recordings, but pleased to report that Trent has done a superb job of cleaning up the tapes and the audio quality doesn’t hamper the listening experience one bit.

The music varies between good and excellent. ‘Free jazz’ barely covers it – the material is actually generally meticulously composed and arranged (featuring memorable, catchy melodies), though there are improvised sections which mainly serve as connecting interludes.

If you want to hear a collision between Sonic Youth, Ornette Coleman and Gyorgy Ligeti, enlist here. It’s a no-cliché zone, guaranteed to annoy the neighbours, and a valuable detox from the mainly safe, secure sounds of today. Quartet (England) 1985 is highly recommended and a fine 40th anniversary celebration of the 1985 tour.
