The fourth installment on Irenic’s main outlet is done by Canadian dub meister Altitude, also know as Matt Thibideau. He serves up two tracks: the first is a classic Altitude jam, deep, heavy on the dub but still packing a punch. The second track is a headier workout, which might also attract some house enthusiasts with it’s deephouse orientated basslines and lush chord progressions. On the b-side the well respected dub producer grad_u takes the a1 track and completely flips it on its head; a long heavy dub techno trip, not for the faint-hearted.
