Reaction is beginning to come in as Radiohead's new, variable-pricing album went on sale on Tuesday. The reviews are largely positive. Yet a spokesperson for the band said that figures on how many copies were purchased or what prices were paid were not yet available, and might never be, according to a new Associated Press report.

The report also said that in the band's only recent interview, guitarist and instrumental wizard Jonny Greenwood explained to Rolling Stone that the band opted for the unusual release "partly to get it out quickly, so everyone would hear it at the same time, and partly because it was an experiment that felt worth trying."

On the optional pricing, he said: "It's fun to make people stop for a few seconds and think about what music is worth, and that's just an interesting question to ask people."
