Finally there is music to enjoy from Kaduatan, the musical project from John and Paul Quijada (long time fans of 1970s Italian progressive rock AND the invented languages of Magma).

John's most complete language, called Ithkuil, was discussed at length in a New Yorker magazine article in 2012.

Quijada’s entry into artificial languages was inspired by the utopian politics of Esperanto as well as by the import bin at his local record store, where as a teen-ager, in the nineteen-seventies, he discovered a concept album by the French prog-rock band Magma. All the songs were sung in Kobaďan, a melodic alien language made up by the group’s eccentric lead singer, Christian Vander.
Anyway, John is a good friend of mine, and he has been working for years on combining his love for progressive rock music with his language Ithkuil, which has become pretty widely known in the world of con-lang, or constructed language.

The first song is a 14-minute song called "Ozkavarkúi (“Guessing Games”)", and features vocals by the guy who designed two of the constructed languages you hear on the Game Of Thrones TV show.

I think it's pretty cool: check it out!
