There is music of different genres in Esperanto, including folk songs, rock music, cabaret, songs for solo singers, choirs and opera. Among active Esperanto musicians is for example Swedish socio-critical music group "La Perdita Generacio", Occitan singer "JoMo", the Finnish group "Dolchamar", Brazilian group "Supernova", Frisian group "Kajto" or Polish singer-songwriter Georgo Handzlik. Also some popular music writers and artists, including Elvis Costello and American singer Michael Jackson recorded songs in Esperanto, composed songs inspired by the language or used it in their promotional materials. Some songs from the album Esperanto from Warner Bros., which released - all in Esperanto - in Spain, in November 1996, reached a high position in the Spanish record charts; similarly, in 1999, in Germany, hip-hop music group "Freundeskreis" became famous with their single "Esperanto". Classical works for orchestra and choir with texts in Esperanto are "La Koro Sutro" by Lou Harrison and "The First Symphony" by David Gaines. In Toulouse, France, there is Vinilkosmo, which produces Esperanto music. The main internet Esperanto songbook KantarViki has got 3,000 songs in May 2013, both original and translated.
