It's why I posted that Rundgren interview some pages back. He's absolutely right that the human brain has limits to how much information it can comfortably and enjoyably process. Go beyond that limit, and the brain gets overwhelmed and fatigued. Rundgren's also right that the failure/inability to tour hurt the band in several ways. First, by restricting the band's exposure, it hurt album sales, especially with the waning popularity of MTV. Second, and perhaps more important, it made XTC a hermetically sealed band. Touring gives a band instant feedback regarding what works and what doesn't. It also gets the band away from the studio. Given free rein over ever-expanding technology, Andy produced increasingly synthetic music. I own every XTC album, but after O&L I find them increasingly less enjoyable to listen to, even though I admire the craft that went into them.
