Fredrik Thordendal (born February 11, 1970) is the lead guitarist and a founding member of the Swedish metal band Meshuggah.
Under the name Fredrik Thordendal's Special Defects, Thordendal released a solo album in 1997 titled Sol Niger Within with Ultimate Audio Entertainment. The album was remixed and re-released by Ultimate Audio Entertainment and Relapse Records in 1999 under the title Sol Niger Within version 3.33. The re-release contains two bonus tracks but omits several parts of the original version.
As a guitarist, Thordendal draws attention with his clean, flowing, jazz influenced lead playing and powerful, rhythmically complex rhythm playing, augmented by his use of low tuned eight string guitars. Most notable is the similarity between his solos and those of legendary jazz guitarist Allan Holdsworth. He also contributes to the songwriting for Meshuggah, as well as providing backing vocals in live performances.
Thordendal is also a producer of some note, having produced all of Meshuggah's recent material and also releases for various other bands, Switzerland's Fragment among them.
