obZen is the sixth studio album by Swedish extreme metal band Meshuggah. It was released in Europe on 7 March 2008, and in North America on 11 March 2008 by Nuclear Blast. Tomas Haake made his return as a studio drummer for the record after the Drumkit from Hell drum software was used on Catch Thirtythree. It is also the first album on which bassist Dick Lovgren performs despite having been a member of the band since 2004; this is due to the bass having been digitally programmed on the previous album, Catch Thirtythree, and the bass having been performed by guitarist Fredrik Thordendal on the previous I EP. The release of the album was followed by their first world tour. A music video was filmed for a shorter version of the song "Bleed". A two-disc vinyl re-issue was released on 22 March 2019 through Nuclear Blast. A remastered version was released 31 March 2023 for the 15th anniversary through Atomic Fire.
