Tess Wiley was a member of Sixpence None the Richer from 1995 to 1996. She contributed rhythm guitar and backing vocals on many songs on the albums This Beautiful Mess and Tickets For A Prayer Wheel. She also sang lead for some portions of Dresses. She wrote Disconnect.

Her post-Sixpence career has shown her playing with several other bands (including Velour 100 and Phantasmic). She soon began releasing songs as a songwriter in her own right - originally under the name Tess Wiley & Her Orchestra, but eventually as just Tess Wiley. Rainy Day Assembly was released in 2001.

Her most recent album, Not Quite Me was released in 2004. A new album is currently in the works.
