A brooding meeting between free improvising double bassist Joëlle Léandre and Catalonian drummer/percussionist Nuria Andorra (Icarus Ensemble, Barcelona 216, Patchwork Ensemble), two generations of improvisers finding common ground through a simmering boil of intelligent improvisation, imaginative technical skill and passionately assertive playing.

Referencing geothermal physics in the titles of their improvisations, these three Spanish improvisers create a riveting and radical set of experimental works, with Irene Aranda working inside and out of the piano, Johannes Nastejo extending and adapting his double bass, and percussionist Nuria Andorra using an arsenal of metallic and percussive objects.
