Meshuggah was formed in Umeå in 1987; two years later, the band released their first record, an EP entitled Psykisk Testbild (which can be roughly translated as "psychological test picture", perhaps in reference to a Rorschach Test image). This recording displayed a straightforward thrash metal influenced sound, with some strains along the lines of Metallica's concurrent releases. There were also hints of more complex music in the songwriting. As the group grew older, they further refined the technicality of their musicianship and songwriting. This lead to a harsher sound with it bordering on the lines of an esoteric feel. Some consider it hard to appreciate but it is widely embraced by Meshuggah fans.
