Alive! - Kiss

The standard from which all live albums that have followed are measured against. At the time, this was an absolute earth shattering groundbreaking album. Kiss Alive is considered by many to be the best live album of all time, and is one of the band's high points. There are also Alive 2 (1977), Alive 3 (1993), and Symphony: Alive 4 (2003), but the original is still the best. You asked for the Best, you Got the Best! ;)
