Hot 97's Funkmaster Flex continues to call out artists to release new music. On his show last Thursday (10/20) he challenged Philadelphia Hip-Hop band The Roots to release new music.

"Did I challenge The Roots to get me two new songs?" Flex asked. "Yeah oh yeah. DJ Questlove are you ready? Black Thought are you ready? Cosmic Kev are you ready?"

Flex has challenged several artists to release new music over the last few months including Ghostface Killah & Raekwon, Busta Rhymes, and even Swizz Beatz to provide unreleased tracks by the late DMX.

In a recent interview with HipHopDX, Roots drummer Questlove discussed the status of the upcoming Roots album and why it isn't finished yet.

The Academy Award-winning director, producer, and musician said that his critically acclaimed film, Summer Of Soul (Or, When The Revolution Could Not Be televised), derailed the production of the album. "Here's the weird thing," he said. "In a normal world, I would have done this film, it would've came out and I would have promoted it for eight to twelve weeks. A funny thing happened — Disney was like 'Hey this is Oscar caliber' and I'm like 'Huh? You sure?'"

Quest called the Oscar win a welcomed speed bump.
