On Future Days, Can fully explored the ambient direction they had introduced into their sound on the previous year's Ege Bamyasi, and in the process created a landmark in European electronic music. Where Ege Bamyasi had played fast and loose with elements of rock song structure, Future Days dispensed with these elements altogether, creating hazy, expansive soundscapes dominated by percolating rhythms and evocative layers of keys.

Vocalist Damo Suzuki turns in his final and most inspired performance with the band. His singing, which takes the form here of a rhythmic, nonsensical murmur, is all minimal texture and shading. Apart from the delightfully concise single "Moonshake," the album is comprised of just three long atmospheric pieces of music. The title track eases us into the sonic wash, while "Spray" is built around Suzuki's eerie vocals, which weave in and out of the shimmering instrumental tracks. The closing "Bel Air" is a gloriously expansive piece of music that progresses almost imperceptibly, ending abruptly after exactly 20 minutes. Aptly titled, Future Days is fiercely progressive, calming, complex, intense, and beautiful all at once. It is one of Can's most fully realized and lasting achievements.
