Yeah Presence was a rough patch for the band. Plant had a car wreck in '75 that put him in a wheelchair for awhile, which killed part of the Physical Graffiti tour and put a damper on Presence. Then Plant lost his son a few years later.

Twilight is a great way to describe it. I think they peaked as a group leading up to the accident in '75. The Earl’s Court '75 performance is my favorite because they’re so tight, they were lightning captured. It’s bittersweet to watch knowing they would never get that back shortly afterward.
