This is Waldo, the lead singer of death metal band Hatebeak. Hatebeak is the only band in the world to have an avian vocalist. The band never tours as the amplification required could harm Waldo.Waldo is a a 21-year-old Congo African grey parrot. According to the band, “Waldo is quite talkative and has always responded to music in general. We can tell he likes metal because he stands on one leg when he’s happy. He gets very hyper and talkative when we play music he likes and we usually record his outbursts following an extended listening period. We take the best parts and track them with the rest of the music.”Here is Waldo rocking out:
