I tend to avoid live albums because they usually highlight deficiencies while failing to capture any of the excitement of the event. Even so, I own some superb and well-regarded examples by such as Thin Lizzy, Blue Oyster Cult, UFO and Status Quo. None are as good however as "Stupidity" by the classic original Dr Feelgood line-up.
By the time the booming bass rhythm of "Roxette" starts up, you almost feel as if you're in the audience marvelling at the best three-way rhythm section in British rhythm and blues. This is what the Stones started out doing, but executed with a tighter groove. It builds from a brief, relatively routine version of a Chuck Berry song into a series of classic performances. It's characterised by Wilko Johnson's distinct, choppy guitar playing against Lee Brilleaux's vocal and harmonica, yet also underlined by bass and drums. The band seem to reach a peak with "Going Back Home" from which they never come down.
"Stupidity" is unlike other acclaimed live albums of the 1970s in not being a heavy-riffing, hard rock album nor is it a double-set, though some good bonuses have been added to the CD release. But you'll never hear a better example.
