R.E.M. famously didn’t tour behind its two best-selling albums — 1991’s ‘Out of Time’ and 1992’s ‘Automatic For the People’ — but the band did play a single concert in support of the latter record, a Greenpeace benefit at the 40 Watt Club in Athens, Ga., exactly 20 years ago tonight.

Anyone who saw the ‘Monster’ tour in 1995 no doubt remembers that ‘Country Feedback,’ off 1991’s not-toured ‘Out of Time,’ was the set’s highlight, capped off each night with a mesmerizing solo from Peter Buck — a guitarist not generally prone to long turns in the spotlight.
