Copenhagen Jazzhouse is the official center of Copenhagen's thriving jazz scene, opening in 1991 to fill the void made when Jazzhus Montmartre closed some years earlier. The venue presents around 200 concerts a year from visiting stars as well as the more interesting acts of Copenhagen's homegrown scene, and is known for its intimate performances enjoyed by audiences huddled around candle-lit cafe tables. The lively program offers a combination of classic jazz, swing and more experimental, modern jazz and is one of the key venues for Copenhagen's annual Jazz Festival held in July. From summer 2012, Copenhagen Jazzhouse will have two new stages, the "Stor Scene" (big stage) and the "Lille Scene" (small stage). While most concerts start at 8pm, there are late-night concerts from 11pm every Friday and Saturday under the headline "Natjazz". Copenhagen Jazzhouse opens on June 1 2012 after extensive renovation.
