“Gísli Magnússon’s piece Svartifoss depicts a waterfall in his native Iceland, and is a stunning example of how to create texture.”

“Zijn muziek doet mij soms denken aan die van Iannis Xenakis. Hij schept klanklandschappen en heeft een grote interesse in de specifieke kleuren van de verschillende instrumenten. Er zijn ook grote contrasten tussen kaalheid en muzikale drukte. Ik ervaar zijn stuk als een tocht door een landschap.”

“His music sometimes reminds me of Iannis Xenakis. He creates soundscapes and has a great interest in the specific colors of the various instruments. There are also great contrasts between baldness and musical bustle. I experience his piece as a journey through a landscape.”

"...en blød akustisk klangundersøgelse af metal og træ, med pauser, der skærper lytteopmærksomheden til det yderste."

"...a soft acoustic sound-study of metal and wood, with pauses, that sharpen the listening attention to the utmost."

„Það var reyndar verkið eftir hann Gísla sem stóð upp úr, fyrir mér allavega... Það var mjög skemmtileg uppbygging í því... og svona skemmtilegur leikur milli fiðlunnar, hörpunnar og slagverksins. Mjög fallegt! Skemmtilegt verk!“

"It was actually the piece by Gísli that I enjoyed most... the development was really interesting... and a fun interplay between the violin, the harp and the percussion. Very beautiful! Enjoyable piece!"
