US musician and Apple fan John Mayer will make four live recordings available for download from the US iTunes Music Store.

The recordings – from his current US tour – will be called As Is. The first version, recorded at Mountain View, California, includes ten tracks, and costs $9.99. It is not possible to buy tracks independently of the album.

iTunes will sell a ten-song album from each concert on each New Music Tuesday between now and August 31. The album will be available on iTunes for a month, after which it will also be available on other services.

Apple has had a history of working with Mayer in the past, with his most recent appearance alongside Apple CEO Steve Jobs at Macworld Expo for the debut of GarageBand.

Apple vice president of applications Eddy Cue said: "We're thrilled to be working with John to give iTunes users the opportunity to purchase and download some of his recent concerts. This exclusive offering is a great example of the power of digital music and its ability to quickly bring unique and compelling content to hungry music fans worldwide."

Mayer, 26, says he called this collection "As-Is" because: "What you hear is what you get. The wrong notes are as wrong as the right ones are right. In the end, the way the songs make you feel is the only thing that matters."

It is not yet clear whether the "As Is" albums will be available in Europe.
