Atolón : Ruth Barberán, Alfredo Costa Monteiro, Ferran Fages. Chip shop music : Erik Carlsson, Martin Küchen, David Lacey, Paul Vogel. Recorded by Simon Reynell, February 2012. Mixed and mastered by Ferran Fages. A collaboration between two established and highly-regarded improvising ensembles, Atolon from Barcelona and the Irish-Swedish group Chip Shop Music. The disc consists of the whole of a wonderful concert performance from February 2012 in which the two groups attempted to play together without merging or compromising each group's sound, and a studio piece that combines recordings by the two groups which were made separately and then superimposed.
