Association of DJs and MCs in Irun. Very often they have added the last note in Fermin‚s concerts, and what they are now presenting is the session that took place in the concert hall Zambra in Lesaka with Fermin Muguruza Kontrabanda. Hip hop, rap, dance hall, ragga, free style… In the last few years in the Basque Country Bad Sound System has undergone a shaping process. We have chosen the most powerful “riddims” from Stepi Selectah’s Reggae-Dancehall sessions. Masta from Imperio Sabio as well as Brujo from HR and Kenitra MC have been important factors in this shaping. After fitting Masta, Brujo and Kenitra’s rhymes in classical reggae sounds, in 2003 we made several concerts with DJ Sucio’s help in Lesaka (Zambra concert hall). We have compiled the concert made with Fermin Muguruza Kontrabanda on the 3rd of January 2004 thanks to KONTRAKALEA’s help.
