Van Coke and songwriter Hunter Kennedy have gone on to explore other genres of music also not previously popular in Afrikaans and have ventured into more commercial routes. Shortly after the arrival of this and other rock acts, the first Afrikaans television music channel (MK89) was opened which focused mainly on rock music. The Afrikaans (and English) rock and alternative music scene has been booming ever since. Bands like Battery9, Terminatrix, NuL, K.O.B.U.S. and Thys Nywerheid continue to reinvent alternative Afrikaans music, while Jack Parow has continued the Cape's development of Afrikaans rap from pioneers Brasse vannie Kaap, finding success as far afield as Holland with his 2009 single "Cooler as Ekke". 2009 Breakthrough Experimentalism From 2009 into 2010, two unique and eclectic but thoroughly South African groups in particular received high acclaim from international music media, and both groups challenged traditional genre descriptions. They significantly increased global recognition of contemporary South African music culture. BLK JKS' experimental Afro-rock took inspiration from The Mars Volta to blend their Zulu heritage and township origins with modern sounds and equipment and an approach to music-making that seems entirely devoid of boundaries, while maintaining the sweet melodies and rhythmic qualities of South Africa's traditional music. They received an important boost after performing in Opening Ceremony of 2010 FIFA World Cup. Die Antwoord has challenged conventions of hip-hop through its blend of English, Afrikaans, and local slang, and sparse House-influenced production, reflecting the new 'Zef' counter-culture in its cheap-and-dirty values. The band achieved worldwide attention with their self-published debut thanks to two striking and humorous YouTube music videos released in 2010 that rapidly reached viral proportions. The highly polarised international response to their music helped them secure an album deal with Cherrytree Records, an imprint of Interscope. They also famously triggered a feud with American pop singer Lady Gaga, who offered them the chance to open for her on her Born This Way Tour, which they blatantly refused. In 2016, singer Refentse Morake made waves for releasing his debut album solely in Afrikaans, becoming the first black singer to do so. Drum and bass The South African drum and bass scene began in the mid nineties. In 2000, events such as Homegrown became a prominent fixture in Cape Town and a launching platform for international and local artists such as Counterstrike, SFR, Niskerone, Tasha Baxter, Anti Alias and Rudeone.
