13. Oasis (1996)
Oasis were well into the debauched (What's the Story) Morning Glory? tour when they agreed to an MTV Unplugged taping at London's Royal Festival Hall. It was a rare chance to see the group outside of a stadium or giant festival, but shortly before showtime Liam Gallagher backed out due to a "sore throat." Most groups would never dream of playing a gig without their lead singer, but his brother Noel simply shrugged it off and decided to simply take over vocal duties. After all, he wrote the songs himself and was a great singer in his own right. Making the night even more surreal, Liam decided to sit in the audience and heckle his own band throughout the show. There's never been anything like it in rock history. And it was probably the first time Noel realized he could do all of this on his own.
