Jan Steele/John Cage: Voices and Instruments [Antilles, 1977]
Produced by Brian Eno for his own Obscure labels, this hath charms to soothe the aging punk. It's rock only by association--Steele is aided by a "very quiet, repetitive" rock-improvisation ensemble called F & W Hat, while Cage makes use of the voice of the pataphysical Robert Wyatt. But if the idea of devotional music for secular people appeals to you, and if you find ECM "jazz" impressionistic and unstructured, keep your ear out for this.
