Esbjörn Svensson Trio (or e.s.t) were a Swedish jazz piano trio formed in 1990 with Esbjörn Svensson (piano), Dan Berglund (double bass) and Magnus Öström (drums).
They are not to be confused with Electro Shock Therapy or an Italian band EST, which has an album listed here: Mostrati.
At 16 Svensson gained a place at the Royal College of Music in Stockholm, going on later to study Music at Stockholm University.
During this time he played in a number of small jazz combos in Sweden and Denmark before finding work in the recording studios.
The trio, founded in the early 1990s, played an unclassifiable brand of music which incorporated avant-garde jazz, contemporary rock and elements of modern classical music in constantly varying proportions.
Esbjörn Svensson was born on April 16 1964 at Västeras, Sweden.
His mother was a classical pianist and his father a keen jazz enthusiast, and the boy grew up with an equal love for both genres, as well as for rock.
He took up the piano "because we didn't have any other instrument in the house", although he would have preferred the drums.
