If someone asked me which records best capture the atmosphere of live rock, I would name these five albums. All of them convey the energy of the hall and of the band, and that primal, raw power of a live performance. There is almost no overdubbing or elaborate studio processing in them, and that is exactly their uniqueness. Live albums are the only surviving document of performances that will never happen again. Five records, five venues, five evenings that now exist only on vinyl.
