Nearly a decade after being discovered by Aphex’s Rephlex label, Gianluigi Di Costanzo is up to his old tricks under the Bochum Welt name. Elan is a listening album for Welt fans, showing Di Costanzo’s long-lasting love of both lush and angular textures, like the powerful hum of noisy feedback over muted notes in “Joystick Coupler,” punctuated with the Kraftwerk-like electro that marked his early compositions (“D.V.E.”). Those who remember the Welt’s sweeping melodic strokes will not be disappointed: it’s this former trancemaster’s atmospheric touch that carries ballads like “Blue Part 3” somewhere off into the rosy-hued sunset.
