Amerigo Gazaway has made a name for himself as an ingenious mad scientist of sorts, one who uses his musical beakers to create an amalgam of two entirely separate yet somehow synchronized artists. In his mashup arsenal thus far is 2011’s Fela Soul (ingredients: Fela Kuti & De La Soul), 2012’s Bizarre Tribe: A Quest to the Pharcyde (ingredients: A Tribe Called Quest & the Pharcyde), and 2014’s Yasiin Gaye (ingredients: Marvin Gaye & Yasiin Bey, fka Mos Def). Today, he has made his latest creation available for free, and it may be his cleverest yet. The Trill Is Gone combines the iconic Blues guitar of the late B.B. King with the Southern trappings of UGK, Texas’ Underground Kingz featuring Bun B and the late Pimp C.

As with his previous work, this album manages to pay homage to all parties involved, but this one strikes a particularly poignant chord, both in content and title. B.B. King passed away earlier this year, just a few months shy of his 90th birthday. And, as most Heads know, Chad “Pimp C” Butler tragically died in 2007, making The Trill Is Gone not just the latest in a series of imaginative musical feats, but a tribute album unlike any other. The 17-track project features songs with Bubba Sparxx, Eric Clapton, Juvenile, Ludacris, Outkast, Scarface, Talib Kweli, and many others and is now available for free download thanks to Soul Mates Records and Gazaway’s official Bandcamp page. R.I.P. to two legends who are gone but not forgotten.
