a broad genre of rock music started by psychedelic bands that focused on musical reinvention and innovation. lyrics were more poetic, songs were longer and more complex, technology was harnessed for new sounds, music approached the condition of "art" and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening rather than dancing.
