What's the average life span of a band?
The great bands might have 7-8 years; the good ones, maybe 3-4, but the average band usually dies after the release of their first record. Every band runs its course.
As for the power-pop band Jellyfish, they managed to release a second record but by that time the band had already reached its demise.
Jellyfish's debut album, Bellybutton, was released in 1990, drawing on a wide range of influences: The Beatles, Queen, Badfinger, XTC and The Beach Boys (to name a few).
Bellybutton contained the commendable singles, "That Is Why," "I Wanna Stay Home," "Now She Knows She's Wrong" and "The King Is Half-Undressed." However, "Baby's Coming Back" was the band's most successful single, peaking at #62 on the Billboard Hot 100 Chart.
Before the band recorded its second album, Spilt Milk, guitarist Jason Falkner and bassist Chris Manning left the band. Falkner wanted to record his own songs, while Manning grew tired of touring.
Drummer/vocalist Andy Sturmer and keyboardist/guitarist Roger Manning released Spilt Milk in 1993, but creative differences resulted in the band's break-up the following year.
Since then, Andy Sturmer has composed, produced, and recorded with The Black Crowes, Ozzy Osbourne and The Merrymakers.
Roger Manning was a member of Imperial Drag and has played with Air and Beck. He released his first solo album in 2005 entitled, Solid State Warrior.
Jason Falkner has played with The Grays and has since reunited with Roger Manning to form TV Eyes. Falkner and Manning have also played on Cheap Trick's The Latest.
Chris Manning is now a producer and engineer who has worked with Santana, Metallica, Third Eye Blind and Guster.
