Mattias began drumming at the age of six; when he was thirteen, he began playing guitar. He has named Frank Zappa and Kiss as his two major musical influences, but his record collection also included gypsy jazz, Miles Davis, and Slayer among many others.
In the mid-80's, Mattias joined the band Frozen Eyes. Frozen Eyes split up soon after their self-titled album was released in 1988 and Mattias subsequently joined Danish metal band Fate as lead guitarist. Mattias appears on their 1990 album Scratch 'n Sniff. He later returned to Sweden, forming his own band Freak Kitchen in 1992 with former Frozen Eyes drummer Joakim SjÃ¶berg and bassplayer Christian GrÃ¶nlund. The band played together for 8 years, until SjÃ¶berg and GrÃ¶nlund left in 2000, only to be replaced by Christer Ã–rtefors and BjÃ¶rn Fryklund. Outside of Freak Kitchen, Eklundh has recorded several solo albums, and made appearances as a guest musician for Swedish heavy metal bands like Evergrey and Soilwork. His two Freak Guitar solo albums are released on Steve Vai's Favored Nations label, and include drawings and other artwork by friend Anders Nyberg. In 2005, he grouped with Swedish bass guitarist and composer Jonas Hellborg in the Jonas Hellborg Trio along with drummer Niclas Campagnol and played their first gig in Mumbai, India and followed with a tour of India. His album "Freak Guitar - The Road Less Traveled" features a rock/metal-like remix of not title theme, but the background theme from the 1985 film Fletch.He also annually hosts and teaches at the Freak Guitar Camp. Mattias Eklundh endorses Caparison Guitars, who make his signature Apple Hornguitars, and Yamaha Guitars for the company's unique Silent Guitar electroacoustic. He is also a long time user of Laney amplifiers, currently using a VH100R. Russian manufacturer AMT Electronics have created a signature overdrive/distortion pedal for Eklundh called the Freak Guitar. Recently, Mattias Eklundh became a devoted Kelstone user.
