Guitarist and composer Guillermo Celano is a native of Buenos Aires, Argentina. However, he has been a resident of Amsterdam for many years. In 2013 Guillermo was assigned festival composer by North Sea Jazz Festival.  In addition to Wild Man Conspiracy Guillermo is also currently working with the Celano/Baggiano Group, Lila’s Déjà vu (with Ingrid  Laubrock) and Thelonious4. According to Troy Collins: “Celano is emblematic of New Dutch Swing,…his respective knack for integrating multiple genres into a cohesive writing style facilitates a wide spectrum of sonic possibilities” (pointofdeparture ,USA, June 2011).

Marcos Maggi writes about Celano: “Frightening, psychedelic, alien!
 It proposes another mindset, another connection between the music and the listener … a powerful intergalactic trip” ( Cuadernos de Jazz, Spain, June 2011)
