A new recording of the complete string quartets by Reich — Different Trains, Triple Quartet and WTC 9/11 — was recently released by the Mivos Quartet, featuring involvement from the composer. Steve Seel spoke with Reich by phone about his unlikely history of string quartet writing and his unusual approach of "multiplying" the quartet with prerecorded tracks. Listen using the player above.
