50 Foot Wave are a power-pop trio founded in 2003. Principal lyricist Kristin Hersh (the other band members share songwriting credit), also the founder of the closest thing to open source the music industry has ever had, CASH Music, sees this project as somewhat mathematical - 50 feet is the wavelength of the lowest audible (to humans) F tone. But it's more than that - it's very much an emotional roller coaster.
This song, an early single by the group, is very much a bombastic thrill ride from start with finish, with unabated guitar and raspy growl by Hersh, bass by Bernard Georges, and the drumming of Rob Ahlers. The personal nature of the song - the lyricist tends to write and perform in first person - is clear.
