Mixtape Mondays kicks off this week with sets featuring the sounds of the Beastie Boys, Sango, James Murphy and Trillwave 3. DJ AllyAl starts the roundup with a heartfelt set dedicated to the Beastie Boys that focuses on their b-boy ready tunes from the mid-80s into the early 90s. Anthony Valadez brings Sango into the studio for a fireside chat and delivers a dope mix of sounds from the budding star from Michigan. James Murphy keeps things going with his Not-So-Summery Summer Jam. The Hood Internet closes things out properly with a massive dose of trap rock on Trillwave 3. Click through to check the tunes.
