Ishibashi's main instrument is piano, though she is adept at drums, flute, and vibraphone. She received formal musical training in childhood through the high school in her hometown of Monbara in Chiba Prefecture. She began to pursue a career in music as a drummer in several bands including Puff Puff. She also worked as studio musician for many Japanese artists on piano and vibes.
Her first "solo" recording was Slip Beneath the Distant Tree in 2007, a double-length duo offering with Ruins bassist Tatsuya Yoshida. She followed it a year later with the innovative Drifting Devil. The album captured the critical imagination of Japanese journalists -- many of whom selected it as one of the year's best recordings -- as well as the admiration of fellow musicians, and her reputation grew. Ishibashi was working constantly both in the studio and on the road with an entire range of players in addition to performing her own shows. 2009 saw the release of the collaborative trio album Maboroshi with Gianni Gebbia and Daniele Camarda. The following year she met O'Rourke when they were both invited to play on Phew!'s Five Finger Discount. He asked her to perform on his All Kinds of People: Love Burt Bacharach tribute set that was also issued in 2010, and they joined one another's bands. He produced Ishibashi's 2011 album Carapace, and recorded and mixed her solo piano follow-up, I'm Armed. Both recordings were issued on Felicity. In 2013, she played on Gaspar Claus' Jo Ha Kyū, where she played alongside Ryuichi Sakamoto, Haino and Kazutoki Umezu. She also signed to Drag City. They released Imitation of Life, produced by O'Rourke. She followed it with Car and Freezer in 2014. Ishibashi and O'Rourke were also members of Kafka’s Ibiki, who cut three albums between 2013 and 2014. She played on O'Rourke's Simple Songs in 2015. Ishibashi kept up a rigorous touring regimen that included playing her own shows and with O'Rourke and their band. She also found time to form RNA with Fumio Kosakai and Kimihide Kusafuka and cut the double-cassette release, No New Tokyo. In early 2016, Ishibashi released another duo recording, this one in collaboration with Masami Akita (aka Merzbow); entitled Kouen Kyoudai, it was recorded and mixed by O'Rourke and released on Editions Mego. ~ Thom Jurek, Rovi
