Hatebeak is a death metal band, formed by Blake Harrison and Mark Sloan, featuring Waldo, a Congo African grey parrot (b. 1991). Hatebeak is the only band to have an avian vocalist. They never tour so as to not torture the bird. Hatebeak is signed to Reptilian Records. The band split up in 2009 but reunited in 2015. They released the album Number of the Beak on June 26, 2015, through Reptilian Records.
The band's sound has been described as "a jackhammer being ground in a compactor". Aquarius Records magazine called Hatebeak "furious and blasting death metal". Hatebeak made its second record with Caninus, a band whose lead singers were two dogs. Hatebeak's goal is to "raise the bar for extreme music".
