The HangBrothers project is born in 2013 from the meeting of Sacha “Unity” and Julien “Aslak” and their passion for the Hang and the handpans. (a new family of instruments wich was invented in Bern ( Switzerland) at the beginning of 2000).

The acoustic “Duo” was soon joined by Mercury Fall and his electronic sounds. (others producers, Mantra Flow and Aslak, will also contribute on the electronic side)

​Then two voices come added to the mix. A vocal Yin-Yang with the masculin soul and groovy voice of Daniel “Almacalma” and the light feminin voice of Sophie Rampa, who also adds a few notes of the magical High Spirit flutes.
​Last star joining the “Hang Brothers” constelation in 2015 is an acoustic sometimes electric guitarist “Baptiste Bieri”.


Souloop is an electro-hang project gravitating around Julien “Aslak” Aho & Daniel “Almacalma” Leuenberger, two fine swiss melomaniacs who just love to make music.
They are often joined by their usual accomplices, Sophie Rampa & Sacha Nielsen from the Hang Brothers.
Souloop is a blend of electronic grooves and the mellow energy of the Hang Drum.
Soulful vocals, a dash of percussion and wind instruments round off the ensemble.
Stay tuned for Souloop’s eponymous debut album on Moonloop Records this fall.
