Nine Inch Nails, 'With Teeth' (2005)
After recording the demos that would turn into his 2005 With Teeth, Trent Reznor passed along the rough tracks to see if Grohl would be interested in contributing percussion. After one listen, he said yes. "[Reznor] said, 'When can you start,'" Grohl explained around the time of the record's release. "I said, 'Let's do it tomorrow.'"
