There is even a term for reunited bands that tour their back catalogue for years without releasing any new music called "Pixies Syndrome". The article was speculating whether or not the Stone Roses would release their contracted third and fourth albums once they finish their comeback tour.
"The band could just play the greatest hits for ever like the Pixies do. Somehow the Pixies seem to get away with this, I'm not sure if I have ever seen a bad review of a band who have mercilessly flogged their greatest hits on the live circuit for more than decade. Flogged so much that a reforming band who play no new songs have become called the 'Pixies syndrome'.
What about The Fall syndrome where a band just can't stop releasing records that are still good, like the compulsive new album recording effect that occurs when you happen to be a modern day art punk legend. Or the Portishead Effect when a band returns to form after a long hiatus, and they say shortly after they are going to record a new album but instead the members go on to record a series of rather good solo projects again instead. I'm going to try and think up another before finishing this post, because it needs at least three to be complete, plus the first two I thought up weren't that great and possibly made-up collective psychological conditions that remain to be proven. Or how about The Franz Ferdinand Effect-
The Mutya Effect- suddenly discovering you are no longer a pretty teenage pop princess anymore by being sacked by the management of your band and then subsequently snapped up by a contemporary indie/electro outfit to record a tongue-in-cheek yet still surprisingly really good single collaboration.
I cite the following example from my research as evidence-
That's hilarious. For the past few years I resolved to no longer see bands who reunite just to play old songs. I have come to the opinion that nostalgia is a type of mental cancer.
