Sven B. Schreiber (sbs) Just another piano jazz trio... well, obviously not quite. Here we've got three gifted composers, who put a lot of effort into writing and arranging their complex tracks. Moreover, they master their respective instruments with perfect virtuosity. Jazz the way I love it. Favorite track: Semi-Quasars.

Luc Enjoying the album but the vinyl arrived in a paper inner which has scratched the record and the same goes for other people who ordered the special release with only 30 copies. Real shame but the CD is of course fine to listen too.

Dr. Beaf Ee bah gum, they've done't again. A little more mysterious and darker in some tracks perhaps, but overall a great three piece release. Pretty expensive but still great value; which helps justify the vinyl buy :) Favorite track: Imaginary Limits.

For a group that has been making music since 1999, every album is an opportunity for us to create something new, to test ideas, to challenge ourselves, to break expectations, to bend process, to surprise the listener. This album is our continued attempt at these concepts, and is the collective voice of three musicians operating as one. It’s been a little while in the making… perhaps longer than we had planned…..

We had come to the recording session with a mix of material. Some we had performed live extensively and shaped through those experiences, and there were some new compositions, written specifically for the session and the album.

The Known and Unknown.

Sure, that is an apt description of the material that we approached over 5 days in June 2016, but more importantly it is a representation of the push and pull within improvised music. The known elements, such as written melodies, harmonies and rhythms are combined with the unknown moments… the collective improvised experience, the dynamic and textural changes that happen in the moment and the collective emergent sound created for this precise time only.
For us, the Known and Unknown is the beauty, exhilaration and energy of the music. The music cannot exist without both, and both must remain in balance.

Our hope is that you hear into the music, the layers, the moment, and the melody within.

TRICHOTOMY are one of Australia’s most inventive contemporary music ensembles.
So much more than a traditional jazz trio, this group expands the capacities of the classic piano/bass/drums combination by skillfully blending dense, exciting improvisations and delicate atmospherics, conjuring up sounds of modern jazz, ambient music, avant-garde rock, free improvisation and contemporary classical. ... more
