Magnus Öström was born in Skultuna, Sweden as second son to local painter Arne and Siv Öström. His brother, Tommy, was three years older and influenced Magnus in his early years with his eclectic record collection including Jimi Hendrix, Deep Purple, Allman Brothers and Lynyrd Skynyrd.
At the age of eight Magnus built his first drum kit out of his fathers empty paint cans and only a year later he started his first band together with a kid from across the street, Esbjörn Svensson.
In 1978 his brother took him to a concert of Billy Cobham with John McLaughlin, an experience that turned his musical world upside down and got him into jazz-rock.
In 1985 Magnus moved to Stockholm to study at the Royal Conservatory of Music where he immediately started to play in different bands on Stockholm’s jazz scene. Between 1987 and 1992 he was a constant member of Monica Borrfors’ band, a well-known Swedish jazz vocalist who played mainly jazz standards, and together they toured extensively throughout Sweden and beyond. ”Playing live, especially with a singer is the best school in the world for a young drummer”, Magnus says.
In 1991, Magnus and Esbjörn started the predecessor to e.s.t. and in 1992 Dan Berglund joined in on bass. Together they recorded 12 albums and one concert DVD, toured the world several times over, sold hundreds of thousands of albums, and was titled the ”trio of the decade”. Nowadays e.s.t. is considered to have been the most influential band in jazz in the Noughties and the album Live in Hamburg has been awarded ”Album of the Decade” by no less than The Times (UK).
