Wiz Khalifa and Lil Wayne are gearing up to be apart of a music festival movement this summer.

The Taylor Gang general and Weezy will be headlining Denver’s free music festival, 420 Rally at the Civic Center Park in Downtown Denver on April 16, 2016.

The Denver Annual 420 Rally is a non-profit organization dedicated towards building an inclusive, engaged community that promotes equality in economic justice, access to fair housing, improved education, and greater police accountability and professionalism

President of the 420 Rally Non-Profit Organization Miguel Lopez adds that “Last year, the Denver Post estimated more than 125,000 people attended our gathering; this year, we intend to exceed that and help raise awareness of some of the most pressing political issues facing Colorado and our country as a whole.”
