Slavko Avsenik (born November 26, 1929 in Begunje near Bled, Slovenia) is a Slovenian composer and musician. His career accomplishments place him at the worldwide pinnacle of success among ethnic popular musicians. Over forty years, the Avsenik Ensamble's original "Oberkrainer" sound became the primary vehicle of ethnic musical expression for Slovenia, Germany, Austria, Switzerland, northern Italy and the Benelux countries, spawning hundreds of Alpine orchestras in the process.
The Ensamble, known as "Ansambel bratov Avsenik" or "Slavko Avsenik und seine Original Oberkrainer" has performed before millions, including heads of state, on radio and television, and in thousands of concerts. Selling over 30 million records, Avsenik has earned thirty-one Gold, two Diamond, and one Platinum record. The "Johann Strauss of the twentieth century," Avsenik collaborated with his brother, Vilko, to produce nearly 1000 original compositions and an integral part of the Cleveland-Style legacy. The Avsenik saga began in 1953 with a band formed in Slovenia, broadcast on the Slovenian Hour from Austria, and dubbed the "Musicians of the Oberkrain" by a Vienna disc jockey. Growing in popularity, they soon began appearing in broadcasts, movies, and concerts in West Germany.
