Lundakarnevalen The Lund carnival has been held every four years since the mid-nineteenth century: traditional accounts say it originated at a wedding in 1849 (the four-year intervals place the party in 2002, 2006, 2010, etc.). Arranged by the students of the university, from the 1950s onwards the event has grown in size and intensity (with some 5,500 volunteers 2010), but it remains an amateur event. Midway between a music and stage fair, a city festival, and an outpouring of satire, parody and general madness. Some students dress up in costumes, often relating to and poking fun at current issues, and parade in wagons. Others perform humorous skits in the evenings. The carnival revues and other stage entertainments have launched a number of well-known entertainers and actors over the years. Music Lund has long been a regional centre for classical and church music. In particular, Lund is renowned for its vibrant amateur choir scene, with choirs such as Carolinae damkör, Domkyrkokören, Katedralkören, Lunds akademiska kör, Lund Chamber Choir (Swedish: Lunds Kammarkör), Lunds Studentsångförening, Lunds vokalensemble, and the Svanholm Singers. Since 2006, Lund has been the host of the biannual Lund International Choral Festival. Classical orchestras based in the city include the Lund City Orchestra, the Academic Orchestra and Lund New Chamber Orchestra. In more recent decades, Lund has also developed a lively pop and jazz scene. The cultural venue Mejeriet opened in 1987 in a former dairy building just outside the city park. It has hosted concerts by both well-known and emerging bands. The pop singer and television presenter Måns Zelmerlöw was born and grew up in Lund. Artists associated with Lund include DJ and record producer Axwell, rock musician Kal P. Dal, rapper Timbuktu, indie pop group The Radio Dept.,
