50 Foot Wave

50 Foot Wave (often stylized as 50FOOTWAVE) is an American alternative rock band, formed in 2003. The band is fronted by Kristin Hersh, who writes the group's songs with collaborative efforts from the other group members in composing and arranging the music. The group's name is a reference to both an illustration and the term for the 50-foot sound wave of the lowest F tone audible to the human ear. The band sometimes abbreviates its name as L'~, using the Roman numeral for 50.
