Terry Riley’s In C, performed by Iron Giant Free Association is due July 25th.

The debut album from Birmingham-based music collective Iron Giant Free Association is the culmination of their decade-long relationship with Terry Riley’s 1964 minimalist masterwork, In C. What began as an interest in large-scale multi-instrumentation evolved into years of experimentation and collaboration with Riley’s revolutionary piece.

On stage, they gradually began incorporating elements of improvisation, fixed arranging, and rhythmic/ harmonic manipulation until eventually the piece took on a distinct character-something uniquely their own. In the studio (i.e., their own homes) they would meticulously document this over the course of a year. Hypnotic percussion, swells of synthesizers, mutated AM/FM radios, and punchy bass all emerge in a reimagining of In C unlike any before it.
