Meshuggah, also known as Psykisk Testbild (Pronounced "see-kisk test-build") is the debut EP by Swedish extreme metal band Meshuggah.

The three tracks on this EP were later reissued on the compilation Rare Trax.

Although the EP is known as Psykisk Testbild ("mental test pattern"), this title is not to be found anywhere on the cover itself.

[1] This is the only Meshuggah record featuring drummer Niclas Lundgren.

The track "Cadaverous Mastication" was included on their first studio album, Contradictions Collapse.
