1990s also saw a resurgence in instrumental rock's popularity, and some of the classic bands from previous decades reformed. Surf music also became popular, especially The Argonauts, The Gasolines and Os Ostras. Hard rock had in 1993 a new representative in Brazil, Dr. Sin. Heavy metal had two debuts: in 1990 Torture Squad and in 1991 Angra - all of these are from São Paulo. Also in this period, many other bands acquired widespread national projection, such as: Raimundos (which was formed in the late 1980s, but only released its first album in 1994) with its Forrocore style, Skank and O Rappa, both of which with a style that can be designated like a kind of reggae-rock, Pato Fu as the first indie band that arrived at mainstream, Charlie Brown Jr., with its alternative rock with rap and skate punk influences, and Mamonas Assassinas, who were a great hit with humour and rock but its members died in a tragic plane accident (1996). Also Jota Quest was a success since the first album, 1996, and they arrived with a powerful pop-rock-funk. From the end of the 1980s to beginning of the 1990s names like Planet Hemp, Karnak, Walverdes, Relespública, Virna Lisi, Graforreia Xilarmônica, Okotô and Boi Mamão are prominent. The MTV Brasil Unplugged format brought back to the mainstream some bands whose career had been mainly consolidated in the 1980s, like the Titãs in 1997, Capital Inicial in 2000, Ira! in 2004 and Lobão in 2007. In the beginning of the 1990s there was the Manguebeat (or Mangue Bit) movement that put Recife definitively as one of principal places that has an important modern rock scene. Its style is a cross between the local rhythms, like Maracatu, and rock, hip hop and electronic music. Coming from this movement are Chico Science & Nação Zumbi (who shortened their name to only Nação Zumbi following Science's death), Mundo Livre S/A, Fred 04, DJ Dolores, Stela Campos, Otto etc. Kurt Cobain after his shows in Brazil with Nirvana in 1993 helped spread the Brazilian rock in the world. David Byrne, Beck, Of Montreal, Devendra Banhart and others were influenced by the 1960s Tropicália and have divulged this musical style to the world. In the 1990s, Björk, Stereolab, Towa Tei, Amon Tobin and The High Llamas were approaching the Brazilian pop music increasingly. Between final 1990s and beginning of 21st century are relevant: Los
