„They have the all the trappings of an electronica outfit—the name, the album title (Rec.Extern), the lineage (previous releases on Mego and Rhiz), the black Powerbook, and the Vienna address. But Radian is two-thirds of a jazz band—with members on drums and upright bass alongside synthesizer and laptop. That makes Thrill Jockey a fitting home, where labelmates Tortoise and Chicago Underground also work the tension between the crackle and the hum." David Krasnow, Village Voice, 2002
