 Zaika briefly joined Cariño's Colectivo Dinamite, or Dynamite Collective, but after attending an event in Sao Paulo called Arena Sound System, she decided to concentrate on dub and sound system culture. In 2014, she thus created the Circuito Sound System, or Sound System Circuit, with Bella Orazontes' reggae sound systems, including Desca Reggae, Uai Sound System, Rude Boss, and the Beat Selector Collective.
