Avant-prog

Avant-prog is a music genre characterized by highly complex, dense structures often featuring dissonance and uncommon time signatures, sometimes extending towards atonality, free time, Free Improvisation, and other experimental techniques. The music tends to be more abstract, energetic, and playful, with more extreme cases generating an ominous ambiance and suspense. It is usually compared with Progressive Rock due to both being Rock subgenres that emerged around the same time and focused on intricate arrangements and technical interplay.
