Unlike officially released live albums, often polished later with studio overdubs, bootleg recordings give a truer, unvarnished snapshot of what concerts really sounded like. The onstage alchemy. The bum notes. The real crowd noise. The ragged glory of it all.

Bootleg live recordings have been coveted by music obsessives for decades. Early essentials include the 1969 Rolling Stones boot “Live’r Than You’ll Ever Be.”

With the advent of iPhone in 2007 and other video-camera equipped smartphones, and the 2005 launch of YouTube, it’s now often easy to find bootleg footage online for many concerts almost instantly.

YouTube kind ruined the commercial viability of most officially released live albums, once an easy music biz cash-in. But it’s made a sprawling galaxy of bootleg concert recordings instantly accessible. It seems like a fair trade, at least for fans.
