About This Project


Inspired by the cries and whispers of the world, Donder weaves mental imagery into layers of sound. While the music takes various shapes, fragments of melodies and forgotten thoughts unfold into sonic landscapes with a cosmic dimension.

Donder played its first concerts as a band in 2015 when they represented the conservatory of Antwerp at the Harmos festival in Portugal. In the three following years, they toured extensively in Belgium and abroad and released three albums. It started with ‘Still’ in 2016, recorded in the attic of the local music school where Harrison played his first notes. One year later they recorded a quartet album with Danish reed player Lars Greve in a church in Copenhagen, and after winning the third edition of the STORM! contest they got to release their third album ‘Keukenpraat’ on the Belgian label W.E.R.F. records in fall 2018.

“Donder is a band like no other. They’ve developed an idiom which is entirely their own and which allows them to pursue their own unparalleled vision. What a joy to follow this young trio. Keukenpraat is their best record yet, but it holds the promise that Steingueldoir, Van De Velde en Callewaert are capable of even more beautiful music.” – Written in Music

Harrison Steingueldoir

Pianist Harrison Steingueldoir (°1995, BE) finished his masters degree at the Royal Conservatory of Antwerp in 2017, where he studied piano with Free Desmyter and Erik Vermeulen. Throughout the years Harrison won different awards as soloist and band member and toured through Belgium, Italy, Norway, Denmark, Portugal and Japan with Donder, GYJO and coaching projects with Ambrose Akinmusire and Avishai Cohen. Besides being a pianist, Harrison teaches and composes and arranges for bigband.

Casper Van De Velde
Drummer Casper Van De Velde (°1995, BE) graduated from the Royal Conservatory of Antwerp in 2017 where he studied with Teun Verbruggen, Stéphane Galland and Dré Pallemaerts. He won the Storm! Contest both in 2015 with his duo SCHTNZL and again in 2017 with Donder. In 2016 he was awarded the prize for best instrumentalist at the Tremplin Jazz Contest in Avignon. Casper is also active in bands like Bombataz and An Pierlé Quartet and is involved in theater projects.

Stan Callewaert
Bassist Stan Callewaert (°1995, BE) moved to Denmark in 2016 to obtain a master’s degree in Music Performance at the RMC. In 2017 he also completed his masters at the Royal Conservatory of Antwerp where he studied with Nicolas Thys and Brice Soniano. Besides Donder, Stan is actively involved in the Copenhagen-based trio Lawaai and has been working on a solo double bass album. He has shared the stage with artists like Randy Peterson, Kresten Osgood and Warren Smith and can be recognized by his rather unconventional, textural approach to the double bass.
