September’s here again. The leaves brown, the nights draw in; thoughts and ears turn towards Sylvian’s music.

The exquisite Brilliant Trees, released in July 1984, is one of those collections that I must have owned on almost every format over the years, and probably bought a few times on each.

A period of extreme introspection and even depression descended upon Sylvian following the split of Japan in late 1982.

Although his relationship with Mick Karn’s ex Yuka Fujii (who took the photos in the stylish Brilliant Trees album package) was largely thought to be the main catalyst, it still represented for Sylvian a distressing rupture of childhood friendships.

He later claimed that he could barely stay awake during this period, so degraded were his immune system and emotional reserves.

Sylvian gathered co-producer Steve Nye and some of his favourite musicians at Berlin’s Hansa Studios and RAK in London. Influences came from ambient music, NYC avant-funk, John Martyn, Nick Drake and ECM jazz.

His friend/ frequent collaborator Ryuichi Sakamoto and brother Steve Jansen were the main musical cohorts, though ex-Japan keyboard texturalist Richard Barbieri also appeared to great effect.

Brilliant Trees is very much an album of two sides. The opener ‘Pulling Punches’ is a sweetener, an effective but unrepresentative slice of white funk featuring NYC sessioneers Wayne Braithwaite and Ronnie Drayton on bass and guitar. The nearest thing to the Tin Drum sound, there’s nothing remotely like it on the rest of the album.

What a treat to hear Kenny Wheeler and Mark Isham’s flugelhorn/trumpet breaks on the classic singles ‘Ink In The Well’ (UK #36) and ‘Red Guitar’ (UK #17). Side two is a different matter altogether – it’s dark, foreboding, autumnal.

Sylvian and Nye mostly eschew ‘conventional’ solos in favour of ‘found’ sounds courtesy of Holger Czukay’s Dictaphone (see below) or Jon Hassell’s extraordinary conch-like trumpet, both used to especially brilliant effect on ‘Wailing Wall’.

‘Backwater’ begins with a powerful build up of (sampled?) strings (and check out Jansen’s inspired groove, a queasy 6/4 over a very strange programmed shaker pattern), while the almost hymnal title track is beautifully performed by Sylvian and adorned with a gorgeous ethno-jam outro.

Listening 30 years on, what strikes one is the minimalist nature of the whole album. It has dated remarkably well. Many tracks are built around a cyclical Jansen groove, sparse bass, strong Sylvian melody and then tasteful, painterly touches from clean guitar, piano, Dictaphone or synth.

This stunning collection set in motion a superb four-album run of form for Sylvian. Brilliant Trees is an almost-perfect blend of songcraft and the avant-garde at a time when pop was drawing on jazz, ambient and world music to occasionally spectacular – and commercial – effect (the album reached #4 in the UK charts and sold over 100,000 copies). You might say things were never quite the same again.
