Isray took to Twitter to do some bragging about his acquisitions, and he took the time to demonstrate a little bit of rock music savvy in the process:

"The incomparable David Gilmour.. the greatest 'phrasing' guitarist in the world!! Honored to bring The Black Strat to the public. The most expensive guitar EVER purchased. And for charity!!!"

Primary Income Streams & Multi-Million Contracts

The previous record for most expensive guitar sold at auction was set back in 2005, when one of Eric Clapton's Stratocasters went for $2.7 million, that sale going towards relief in tsunami-battered Asia. Interestingly, a bevy of rock legends helped out by adding their signatures to that guitar, including Clapton, The Who's Pete Townshend, Jeff Beck, Mick Jagger, Keith Richards of the Rolling Stones, and Led Zeppelin's, Jimmy Page – and also David Gilmour of Pink Floyd.
