It’s been five years since we heard from the post-techno duo Laub. Meanwhile, producer and poet/vocalist Antye Greie recorded a string of albums as AGF, guitarist and producer Jotka launched his own web-design firm, and both started families. And, oh yeah, they became blues musicians. Strange as that might seem, Jotka’s weary, stripped-down licks รก la John Lee Hooker and Muddy Waters (no samples here) slouch perfectly over crackling and popping minimal techno beats. And though she sings only in German, Greie’s tough-edged voice nicely rounds out this great, slow-burning return.
