‘An unshackled mind melt of amorphous Berlin School electronics, glistening guitar tones, snatches of disembodied voices and rumblings of percussive melody… an invitation to introspection, turning sky-seeking kosmiche towards a resonant, contemplative core… too busy to be ambient, too zonked to be rock, instead resting on a modern psychedelic perch of its own somewhere in between.’

The recording of a performance at Studio 104, Maison de la Radio, recycling One for Juan from Jimmy Heath’s Love And Understanding LP for Muse, and Watergate Blues and Smilin’ Billy, both from the Bros’ recent Marchin’ On LP.

‘That was the first Heath Brothers album. Stanley Cowell had started the Strata-East label with Charles Tolliver, and they engaged us to do a record. It was a family affair, and we adopted Stanley because we thought he was amazing. That was a different type of record for us. We recorded it while we were on tour in Oslo, Norway. We used to get on the train and travel around Europe, and we’d be playing in these cabins on the train. Percy played a bass with a cello body that Ray Brown created, Tootie and I played flutes, and Stanley played a chromatic African thumb piano. People would stop and listen to us on these trains going from one country to the next, and it was something that they liked. It was like a chamber-music group. So we decided to include that sound on the record.’

The version of Smilin’ Billy is a show-stopper.

From 1963, following stints for Jackie McLean on One Step Beyond and Destination… Out!, this is maybe the great trombonist’s best record, with Wayne Shorter, Herbie Hancock, and Tony Williams — all involved with Miles around this time — and Cecil McBee. Four Moncur originals: bold, free, forward-looking music; but expansive and assured, never forced. ‘Some other stuff’; not full of itself, but a bit different. Try The Twins — dedicated to his two brothers — for a better sense of his musical good humour.
