In the 1990s, many rappers and DJs started to influence Switzerland's musical scene. Such as Black Tiger from Basel was the first one to rap in a Swiss German dialect. Sens Unik from Renens (a suburb of Lausanne) are one of the most important rap groups, merging hip hop with influences from many other styles. Even their first EP included a track in Spanish, due to MC Carlos's Spanish and Galego heritage. Electronica is also part of the Swiss musical experience, Yello's first album came out in 1979, in the 1980s, Touch El Arab scored a hit in several European countries with the song "Muhammar". Producer Pat Jabbar from Basel established his own record company Barraka el Farnatshi in the late eighties, dedicated to music from the Arabic world (especially Morocco) mixed with dance music from the west. While most musicians’ works were based on contemporary Anglo-Saxon music, singer-songwriter Christine Lauterburg took up the traditional Swiss folk music and merged old domestic song with pop and electronic music elements. With her version of the classic Swiss song "S'Vreneli vom Guggisberg", she triggered intense indignation as well as praise.
