Amazon.com Perhaps the least guitar-rock Silos record ever, Heater sounds as though it was built from the rhythm bed up. Nearly every song grows out of an opening groove, whether it be the quick rabbit's-heart thump that pushes an escaping narrator onward in "Prison Song" or the fragile, spare beats that help characters pass the time--or come to terms with its passing--in "Thanks a Million" or "Front Porch." As with any Silos record--and this one's among the group's two or three finest--the songs are the point of the thing, and Walter Salas-Humara's latest batch, written with a handful of collaborators, draws his characters' emotions with the economy and expertise of a great short-story writer, like Raymond Carver with a rhythm section. --David Cantwell
