Tokyo’s Ai Aso (, As Ai) is a Japanese psychedelic pop singer-songwriter whose work has a whisper-thin acid folk quality to it. She started performing as a solo singer around 2000. Her solo work, infrequent collaborations with White Heaven members You Ishihara and Michio Kurihara, Yurayura Teikoku, and Boris bring a level of fragility and hypnotism to the stage recalling lost memories, small flavors of COIL and serial playing on the verge of evaporation.

As for her recent activities, she has performed on bills together with Sunn O))), Boris, Masaki Batoh (Ghost), Touri Kudoh, Kim Doo Soo, Mark Fry, Simon Finn etc.
