EY is a Japanese vocalist and visual artist, best known as co-founder of the influential rock music band Boredoms and Naked City. He has changed his stage name several times, from Yamatsuka Eye, to Yamantaka Eye, to Yamataka Eye and now simply calls himself EY.

EY is a member of the bands Hanatarash, UFO or Die, Puzzle Punks, Noise Ramones and Destroy 2. He is notorious for his vast, confusing discography and countless guest appearances. Notable collaborations include his work with Nam June Paik,Sonic Youth, Yamamoto Seiichi & Yamazaki Maso, Bill Laswell's Praxis and John Zorn's groups Naked City and Painkiller.

As well as his music, EY is famous for his mixed-media style of art that utilises airbrush, marker pen and collage, amongst other materials. His artworks have adorned a number of records, including the majority of Boredoms releases and, perhaps more famously, Beck's Midnite Vultures. Drawing as much from Japanese mythology as from his musical influences, his work aims to complement the music as well as to provide another dimension to the sound.
