The 1976 Christian musical Firewind is a dramatic musical based on the first four chapters of the Book of Acts, focusing on the power of the Holy Spirit and the early Christian community. It was co-written by Terry Talbot, his brother John Michael Talbot, and Jamie Owens-Collins, with music featuring prominent “Jesus Music” artists of the era.
Backstory and Key Artists

The musical was released as an album on Sparrow Records in 1976. A notable aspect of the production was its cast, which included well-known figures from the burgeoning Jesus Music movement:

Barry McGuire (known for his secular hit “Eve of Destruction” and later Christian music work) sang the role of the Apostle Peter.
Keith Green, before releasing his first solo LP, was featured as a performer on the album.
Anne Herring and Matthew Ward of the band The 2nd Chapter of Acts also participated.
Narrative and Themes

The narrative of Firewind is drawn directly from the biblical book of Acts, chapters 1-4. The story covers events immediately following the resurrection of Jesus, including the coming of the Holy Spirit at Pentecost (“fire and wind”), the bold preaching of Peter and John, and the life of the early church as they shared their possessions and spread the gospel.

The album was described as a “dramatic musical” rather than a traditional stage play, likely intended for performance in churches or as a concept album. One story from the time mentions Barry McGuire and Terry Talbot performing segments of the musical in concert during the mid-90s, years after its initial release, rekindling a long musical association.

The music itself was an example of the passionate, sometimes controversial, art of the Jesus Movement, aiming to present the story of Jesus in a relatable and inspiring contemporary format.
