10 Hidden Details You Never Noticed In Hard Rock Songs

10. Sweet Leaf - Black Sabbath

Master of Reality by Black Sabbath has become known as the unofficial blueprint for stoner rock. Ever since its release in the late '70s, the crunch behind Tony Iommi's riffs on this record was influential on everyone from Van Halen to Metallica to Monster Magnet. There's a lot of history in this record, but that doesn't mean the band was all that serious.

Given the more herbally assisted sounds that permeate the record, it's no secret that "Sweet Leaf" has become one of the greatest pot anthems in all of hard rock.

However, if you weren't completely sold on it, the band starts the entire record off by having a huge cough before the main riff comes in. There has been some debate as to who the culprit was over the years, but all signs seem to point to Iommi himself, who presumably took a massive hit before the tape started rolling.

This could have easily sounded unprofessional, but this little cough ended up fitting the aesthetic of the album perfectly, with songs that were designed to have fans space out in their bedroom with a joint in their hand.

"Sweet Leaf" isn't exactly the most mind-altering song in the world, but starting from that dry heave, you know you're going to be in for one of the greatest odes to ganja.
