Assassin, "Theory of Reggaetivity," (Sound Age Entertainment)

One of Jamaica's most underrated yet diverse and creative lyricists, Assassin A.K.A. Agent Sasco releases his first studio album in almost a decade.

In a transition from dancehall, the artist turns his multi-talented hand to releasing a completely reggae album called "Theory of Reggaetivity." With guest appearances from Chronixx and Australian singer Elesia Iimura, Assassin — born Jeffrey Campbell — takes on topics such as achievement, struggle and love with his new album.

Setting fire from the top, the performer examines the birthmarks of reggae with a modern twist on the title track. It's followed by "What is Reggae" and "Reggae Origin," where he simply questions, "Where did it all start? Where did it begin?"

Delivering lyrical precision, Assassin brings humor and energy with "Mix Up," praises the Motherland in fine style with "Africa" and sends a message of perseverance on "Stronger."

Assassin, whose rugged vocals recently cut through Kanye West's "I'm In It" and Kendrick Lamar's "The Blacker the Berry," shows his softer side on the well-written "Day In Day Out," offering a sweet melody that uplifts before taking it back to basics with "Country Bus."
