“Oslo” is about Michael Wollny the masterful auteur of compelling movies, dense narratives, dazzling paintings in sound which occupy the ever-shifting ground between jazz, classical and new music. His award-winning trio receives a whole new sound palette courtesy of the miraculous free improvisers of the Norwegian Wind Ensemble.

From Oslo to the Wartburg Castle at Eisenach is a 1,283 km car journey. It is a distance which can also be travelled by a totally different route, one which also passes through all the changing landscapes in between: you simply stay put on your sofa with your hi-fi in front of you. Michael Wollny has achieved a remarkable feat in making this possible, and the story – with his explanation of how it happened – is well worth telling.

From 5 to 7 September last year, Siggi Loch invited Wollny, bassist Christan Weber and drummer Eric Schaefer to Rainbow Studio in Oslo to record a new trio album. For the third day in the studio, an encounter was arranged with the Norwegian Wind Ensemble, directed by Geir Lysne. This is a group interested in going beyond its own genre, and which also has the capacity to improvise. “After collaborating live a few times, for example on the silent film music for “Nosferatu”, this was simply an attempt to find out if and how things might work out together in the studio,” says Wollny. “It was just another roll of the dice.”

What emerged from the sessions, however, was a dilemma. “At the end, what we had was basically a finished album with the trio, plus a few contrasting takes from the sessions with the Norwegians, sometimes with only three of them, but also with the full complement of 28″. What should we do? Tack these on to an album as an extra CD, a 20 minute test sampler with the ensemble? Or integrate a few songs into the album? That’s what we did in the end,” says Wollny. “They play on the overture, an interlude and finally a quirky coda as a bonus track.”

In that process, the trio didn’t have to forsake its ideas for the new album, quite the opposite. Right from the beginning there had been the desire to make the trio album as richly coloured as possible,” recalls Wollny, “which is also in keeping with what we have been developing live in recent years. And now it has become even more colourful than expected, and right from the beginning: it starts like a fairy tale, becomes funky, and then balladesque. Three entry points into the music. And in addition to these colours, the ensemble becomes part of the kaleidoscope.”

A week later, the trio travelled to Eisenach to give a concert in the Rittersaal at the Wartburg on the occasion of the 25th anniversary of ACT, with saxophonist Emile Parisien invited. Like the Norwegian Wind Ensemble, he added his contributions into the mix in the tiniest of quantities. “Wartburg” was never planned as a record,”says Wollny.” That’s why we didn’t think in quartet format, we simply invited Emile as guest on a few songs.” And then there were practicalities of the venue to deal with: tourists were still being guided through the castle until 5pm, and only after that could the technology be set up in such a way as to handle the idiosyncratic acoustic of the hall. There was no time left for a rehearsal, and the concert finally began at 7:30pm.

So “Wartburg” permits an insight into the very heart of Wollny’s work: improvisation. For some it remains a dark art, there are musicians for whom it is a show-off activity to burnish a reputation, but for him it is a way of being.

“That’s true,”smiles Michael Wollny. “I’m not great at planning ahead. The challenge I set myself is to try to prepare situations that can ultimately evolve into something different. Perhaps it’s a bit schizophrenic.” For him, the point when it becomes exciting is at the precise moment when improvisation kicks in.

“So this is a process which one never really fully understands.Why is this happening right now? Or that? Hm. For me that goes way beyond music. Too much planning hinders the process. The secret of it for me is the capacity to react in the moment.”
