A.R.C. is a collaborative album credited to the trio of pianist Chick Corea, bassist Dave Holland and drummer Barry Altschul, recorded and released in 1971 by the ECM label. The same trio featured on Corea's previous album The Song of Singing, as did an earlier version of “Nefertiti” by Wayne Shorter. The album title stands for "affinity, reality, communication," a term from Scientology, with which Corea had recently become involved.This is the first project in Holland’s long association with ECM.
