Sticky Fingers was a very important album for the Rolling Stones. It was their first disc after Brian Jones left the band and their first full-length LP with his replacement, Mick Taylor. It instantly crushed any doubts that the group was going to struggle without their founding member. It's packed so full of hits that it's easy to overlook the seven-minute epic "Can't You Hear Me Knocking," though over the years, it has emerged as a huge fan favorite.
According to Mick Taylor, the jam at the end was a totally spontaneous moment that the band nailed in a single take. The song sat dormant for a great long time, but in 2002, it began making regular appearances in the setlist.
