Faber & Faber's site hints that Future Days—which is named after Can's 1973 masterpiece—will focus on Faust, Neu!, Can, Cluster, Kraftwerk, Ash Ra Tempel, Amon Düül II—all crucial artists whose works you need in your collection. But I hope he delves beyond these groups, as inspirational bands like Et Cetera, Embryo, Popol Vuh, Agitation Free, Cosmic Jokers, and others still remain largely overlooked. Stubbs is a fine, perceptive writer—I read him regularly in Melody Maker in the '80s and '90s—and I'm confident he'll do the subject justice. Here's a description of his general thrust from the publisher:
Future Days is an in-depth study of this meditative, sometimes abstract, often very beautiful music and the groups that made it, throwing light too on the social and political context that informed them. It's an indispensable book for those wanting to understand how much of today's music came about, and to discover a wealth of highly influential and pioneering artists.
So many of the world's most interesting post-punk, psych-rock, electronic, and ambient musicians from the '80s onward have drawn sonic sustenance from the cream of krautrock. Its ideas are still shaping the outlooks of outward-bound musicians worldwide. Let's hope Stubbs' book doesn't just preach to the converted, but also triggers interest in this music in people who've not yet explored it.
