Any way you slice it, this is not a good thing. The patent should never have been granted in the first place. and restricting live recordings using the patent as a legal weapon is clearly evil.
From RollingStone.com :
In the past few years, fans leaving some concerts have discovered a souvenir far better than a T-shirt: a live recording of the show they just attended. Bands including the Allman Brothers, moe. and Billy Idol have sold instant concert discs, and the Pixies and the Doors plan to launch similar programs this summer. The recording-and-burning company DiscLive estimated on April 12th that it would gross $500,000 selling live discs this spring alone. But in a move expected to severely limit the industry, Clear Channel Entertainment has bought the patent from the technology's inventors and now claims to own the exclusive right to sell concert CDs after shows. The company, which is the biggest concert promoter in the world, says the patent covers its 130 venues along with every other venue in the country. "We want to be artist-friendly," says Steve Simon, a Clear Channel executive vice president and the director of Instant Live. "But it is a business, and it's not going to be 'we have the patent, now everybody can use it for free.'"
