A technical, passionate player, Austrian bassist Adelhard Roidinger has combined his jazz explorations with his studies of computers and technology. Born on November 28, 1941 in Windischgarsten, Upper Austria, Roidinger studied the bass and architecture in college, and eventually began to seriously collaborate with other Austrian and German jazz musicians. One of his first major musical partnerships was when he was asked to play alongside German pianist Joachim Kühn and Swedish trombonist Eje Thelin. In the early 1970s he joined Hans Koller Free Sound, the quartet led by the noted Austrian saxophonist, and appeared on their 1973 album Phoenix. Later in the decade he formed the European Jazz Consensus and released the album Four for Slavia in 1978. The International Jazz Consensus followed shortly after, and their Beak to Beak arrived in 1981. He was able to focus more intently on his own material with his albums as a leader, notably Schattseite (1982). Roidinger remained involved in academia, and pursued further degrees in computer science that allowed him to incorporate computer-controlled visual elements into performances, as well as to compose music via computerized methods. His 1984 album Computer & Jazz Project I showed off what he was capable of in this area, and he won the Ernst Koref Composition Prize in 1988. He has also continued to work as an educator and author in his home country.
