As a composer, Joris Holtackers is fascinated by the fusion of different styles of music and cultures in a stylish & natural way. When performing and playing, he emerges his influences into his very own distinctive style, sensitive and authentic. He can be recognized by a melodically lyrical, a harmonically colorful, and a rhythmically infectious style. His music is filled with character and emotion.
When mixing, Joris tries to re-imagine each musician's flow during the recording. He also thinks like a producer, directing what parts of each instrumental track should be highlighted. He doesn't stop until he thinks everything is sounding in a musically pleasant and balanced way.

His goal is giving each instrument it's own, equally important place. Acoustic ensembles are dynamic and organic species, and they require an organic approach. This means that, in general, presets won't do the trick for him. He's "riding the levels" more often than he's "compressing".

Mixing is a handicraft and he's passionate about it.
When mastering, Joris tries to get an end result that's satisfying on hi-end, hi-fi as well as consumer electronics. Where "balance" is the main keyword during the mixing, the most important thing while mastering is "equality".

His aim is to create a spectral balance, tranquility and a spatiality that's very pleasing on any audio system. Just like when he's composing, performing and mixing, he's at home when he's mastering any music style, especially classical music, world music and jazz.

Mastering is precision- and patience work and Joris is fond of it.

PS: if desired, Joris can make a master very loud, competing with current commercial standards while still remaining decent dynamics.
But personally he prefers the motto:
"Stop The Loudness War!"
• Very, very careful mixing and mastering in the broadest sense of the word
• Using the ears wisely: monitoring at low to medium levels to prevent listening fatigue and hearing loss
• Using quality monitors, different headphones and electrostatic speakers, but also hi-fi gear and small consumer / laptop / iPhone speakers and regularly switching between them
• Being very picky with used gear (microphones, converters, monitoring, compressors, equalizers and reverbs)

Last but not least:
• Respecting the musicians who made the music, and it's style/genre
• Loving each and every step of the process, from start to finish
• Clear communication:
Listening to the exact wishes of all customers and create an open atmosphere in which everything can be discussed
• First listening, then act and support the musicians, turn the best spotlights on and aim them at the performers at the very right moment
• Very devoted and serious attitude, but not afraid of experimenting either (if desired). Experiments always have to be supporting the music itself.

But just like classical music, Joris likes listening to jazz & world/latin artists such as:

Dave Brubeck
Chick Corea
Bill Evans
Bobby McFerrin
Pat Metheny
Michael Brecker
Hermeto Pascoal
Rokia Traoré
Paquito D'Rivera
Dino Saluzzi
Béla Fleck
Trilok Gurtu
The Yellowjackets
Jasper van 't Hof
Ernst Reijseger
Astor Piazzolla
Al Jarreau

…and pop artists like:

Paul Simon
Peter Gabriel
The Beatles
The Band
Jeff Buckley
Steely Dan
Stevie Wonder

As a piano/composition-, computer music- and ensemble teacher/coach, Joris loves to pass on his knowledge of and passion for music and sound to anyone who's interested.
