Hans Tammen calls his style of performance “Endangered Guitar,” because of the extreme alterations he enacts upon his instrument’s sound and construction. Originally inspired by Sonny Sharrock’s and Pete Cosey’s fiery and energetic playing, his rapid-fire juxtapositions of radically contrastive and fascinating sounds capture the energy and abstract musicality that Coltrane brought to the saxophone.
His music has been described as a journey through the land of unending sonic operations, his playing as reverse engineering of the guitar. He recorded with a wide range of artists such as Herb Robertson, Denman Maroney, Günther Müller, Keith Rowe, Alfred 23 Harth, or Dominic Duval - on labels such as ESP-DISK, Nur/Nicht/Nur, Creative Sources, Leo Records, Potlatch, Cadence, and Hybrid. Signal To Noise called his playing “…a killer tour de force of post-everything guitar damage”.
