For his fourth entry in the Madlib Medicine Show series, Madlib heads to the Caribbean. In particular, the blunted Stones Throw'er took a musical flight to Jamaica to create a mixtape of the country's sounds. It all equates to 79 minutes worth of dub, reggae, and roots music, all blended together by Madlib. And it's fitting that this mixtape features an April 20 release date as the CD for 420 Chalice All Stars contains a booklet that lists every medicinal marijuana dispensary in Los Angeles. America's most blunted, indeed.
