Incredible as it seems in this age of merciless repackaging, Outside Society really is only Patti Smith's second 'greatest hits' collection. Culled from her Arista and Columbia albums, taking in everything from 1975's seminal, John Cale-produced Horses to 2007's cover-version project Twelve, it's a remarkably consistent assemblage; Smith, for all her wide-ranging musical and literary influences, having never lost faith with the transformative, tabular rasa potential of rock'n'roll, stripped to its three-chords-and-the-truth essentials.
