On May 1, 2008, when Swedens technical metal giants Meshuggah came to New York on Ministrys C-U-La-Tour, guitarists Fredrik Thordendal and Marten Hagstrom (above left and right, respectively) stopped by MetalKults Manhattan headquarters for a video interview and riff lesson.

Meshuggah were also touring in support of their latest album, Obzen, which was released on March 11 on Nuclear Blast.

In this rare footage, the guitarists talk about their eight-string guitars, extraterrestrial solos, challenging polyrhythms, and time-signature misconceptions, before demonstrating how to play some classic riffs from their catalog, including Rational Gaze, Bleed, Electric Red, Pravus, New Millenium Cyanide Christ, The Mouth Licking What Youve Bled and Future Breed Machine.
