To outsiders, the world of European dance music can seem strange and forbidding. There are flashing lights and fashions to consider, and the music breaks down into subgenres—Italo Disco, Eurobeat, Hi-NRG, etc.—distinguishable only to the indoctrinated. Johan Agebjörn is an insider, but on his first solo album of what he simply terms “disco,” the Swedish producer aims for inclusiveness. Synth-pop standout “The Last Day of Summer” recalls Controversy-era Prince, while “Alice” and the title track revive the accessible bounce of Erasure and Pet Shop Boys. “We’re dancing through the night/That’s what spacers do,” guest vocalist Sally Shapiro sings on “Spacer Woman From Mars,” a dispatch from a surprisingly hospitable planet.
