Jazzpodium trade magazine  (Alexander Schmitz)

“Andreas Brunn is a committed guitarist and composer, an active bridge builder. … “Perpetuum five” comes as an electrified postbop, more grippy, angular, angular, angry, angry, jazzy. Or take “East Side Gallery Story” as the story of a musician who could easily find his way around the world, but instead turns the burden of (time) historical processing and responsibility into music that must be uncomfortable. “

Kieler Nachrichten

“Andreas Brunn repeatedly brings back memories of John McLaughlin. His playing and compositional talent are profound and of intelligent wit; a jazz fugue like “Wizards’ Cube” doesn’t write itself after all “
