"And as we descended, cries of impending doom rose from the soil. One thousand, nay, a million voices full of fear." How Tool recorded a 15-minute song about crying carrots and absolutely destroyed some old pianos in the process

Tool backstage at Lollapalooza at Shoreline Amphitheatre on June 23, 1993 in Mountain View, California.

In the garage at the storied Grandmaster Recorders studio in Hollywood – it's a trendy restaurant now, the heathens – there's a wall full of bullet holes and a helpful piece of graffiti above. It reads: 'Tool shot me here'.

This damaged concrete wall is producer Sylvia Massy's fault and this is how it happened.
