Rather than conventional singing she makes a variety of vocalisations of such a nature that it is often hard to tell that the sounds are being produced by a voice at all.
Her records include Spiritual Voice (1997) and the thirteen track, four-minute EP .
Her 2003 release, Tiger Thrush on the Improvised Music from Japan label, includes 99 untitled tracks.
She has collaborated with a number of other musicians, among them Otomo Yoshihide, Sachiko M (with whom she performs as Cosmos) and Utah Kawasaki (with whom she makes up Astro Twin).
Soba to Bara, a 2009 release on Erstwhile Records, found Yoshida and Toshimaru Nakamura (no-input mixing board) performing one 47-minute improvisation each and pairing the two recordings, each musician's part unheard by the other.
