Starting in 2008, Peter Barthel collaborates with the Grieg Pianoduo, Elles van der Heiden and Siebert Nix, in a project combining 4-hand piano music with astronomy video.
The collaboration featured a world premiere in september 2009, of a new work “The Sombrero Galaxy”, composed for the Grieg duo and Barthel, by Estonian composer Urmas Sisask, for which the composer used Barthel’s Sombrero poster as inspiration. More information can be found in the article on p.16/17 of the July 2011 issue of the Journal “Communicating Astronomy to the Public”. A recent studio performance of “The Sombrero galaxy” can be viewed here.
