Alongside the announcement of Hiero Day’s lineup also comes a few notable anniversaries within the Hieroglyphics’ discography. Souls of Mischief’s debut album 93 Til’ infinity, and Del The Funky Homosapien’s No Need For Alarm are both 25 years old this year, likely prompting special inclusions in the sets. Hieroglyphics’ 3rd Eye Vision is turning 20, while their 2003 effort Full Circle turns 15. To celebrate these anniversaries, Hiero has announced that they will be releasing companion pieces to mark each record, along with never before heard material from the vaults.

Oakland Mayor Jean Quan has officially declared September 3 as “Hiero Day,” and this upcoming Labor Day marks the 7th annual celebration for the west coast crew. The festival and block party promises over 40 musical acts on three different stages and hundreds of vendors in attendance. Tickets are still available.
