Frequencerz

Frequencerz, a Dutch hardstyle music duo consisting of Pepijn Hol and Niels Koster, was formed in 2005. The group's initial breakthrough came through collaborations with other notable hardstyle artists such as D-Block & S-te-Fan and Deepack, who played their tracks at major festivals. In 2009, Frequencerz signed with Fusion Records, and made their debut performance at Defqon.1 in 2010. The duo founded Roughstate, a record label, in 2015 alongside Ran-D, Adaro, and B-Front. They released their first album Medium Rare in 2016 and produced the official anthems for Q-Base and Defqon.1. In 2017, they introduced their live act Stealth Mode at Supremacy and collaborated with B-Front under the alias B-Freqz to release the album Eclipse.
