About Epik1 and SystemIV
Crucial Rhythms was established in 2010 by Brian Chankin and Jeffrey Eckels. Brian "Rad Brian" Chankin and Jeff "Effects" Eckels started the show in 2009, spinning different blends of Reggae vinyl, African music, World Beat and Dub 45s for a year and a half. In 2009, SystemIV started spinning Dubstep along with Rad Brian. In 2013, Rad Brian departed from Crucial Rhythms, and SystemIV hosted the show playing eclectic hip hop singles and interviewing Indy artists until 2016. In mid 2016, Epik1 came on to cohost with SystemIV. Since then the duo has transitioned the show into a Hip Hop Mix Interview show.
