by Bruce EderThe group's only all-instrumental album is alternately enjoyable and maddening. On the down side, there was no earthly reason why Dave Mattacks' drums had to be recorded as loud as they are on certain tracks. But "Portmeirion" and "Expletive Delighted" are as delicate and beautiful as any work that this version of the band has done. Richard Thompson and Jerry Donahue turn up on electric guitar for the rippling finale "Hanks For the Memories," a reconsideration of instrumentals ranging from "Apache" and "Pipeline" to "Peter Gunn."
