Dirty Heads are set to release their most ambitious album to date. The aptly titled Sound of Change, due out July 8 on Allen Kovac's Five Seven Music, is just what it says it is: the band has expanded its sound with tracks varying from club bangers to rap tracks and even to a pop hit, all while maintaining their reggae-rock feel good vibe. For Sound of Change, the band tapped into some of the best producers around to contribute to the album. Grammy award winning producer Supa Dups (Drake, Bruno Mars, Eminem) worked on “Medusa” and “Radio,” Buddah Shampoo (Ty Dolla $ign) co-produced “Silence,” Niles (of hip hop duo, The Cataracs) produced “My Sweet Summer,” David Bassett (Fitz & The Tantrums, Josh Groban) co-produced “Hear You Coming,” LD (aka LDontheCut) co-produced “Franco Eyed” and long-time friend and collaborator, Rome (Sublime with Rome) produced the remaining tracks. The album also features guest vocals by B Real of legendary hip-hop group Cypress Hill on “Franco Eyed,” Tech N9ne (collaborated with Kendrick Lamar and B.o.B.) on “Burn Slow” and Ward 21 (collaborated with Major Lazer, 311) on “Medusa.”
