Strange Euphoria is a career-spanning box set album by Heart. The three-CD compilation features several of their hit songs as well as songs by The Lovemongers, solo songs by Ann Wilson and Nancy Wilson, a recording by the pre-Heart group Ann Wilson & The Daybreaks that goes back to 1968, and previously unreleased demos and live tracks. A DVD is also included featuring a 1976 concert at Washington State University for the Pullman, Washington-based KWSU-TV concert series The Second Ending in promotion for their debut album Dreamboat Annie.
The Amazon.com exclusive version was released with a bonus CD containing covers of five Led Zeppelin songs, entitled Heart Zeppish. As of July 2017, the bonus disc is no longer available.
