In 2014, former Yes vocalist Jon Anderson and Flower Kings/Transatlantic guitarist Roine Stolt began a musical dialogue initiated by Inside Out Music boss Thomas Waber.

Invention of Knowledge is their result.

Co-produced by the artists, it features a prog dream team: Stolt's brother Michael and Jonas Reingold on basses, keyboardists Lalle Larsson and Tom Brislin, drummer Felix Lehrmann, and a five-voice chorus that includes Daniel Gildenlöw.

Waber wanted them to extend the range of "Yes music." That happens, but there's way more to it.

Anderson can still create in the mold of his former band, but he also brings his solo experience that explored a vast range of musical traditions.

Stolt was deeply influenced by Yes, but he's a rugged individualist.

His composing, playing, and modern production ideas are informed by jazz, fusion, electronic, rock, and world musics.

He refracts everything through a third-wave prog prism.
