Performers in Songs from the Heart are vocalists Chloë Agnew, Lynn Hilary, Lisa Kelly, Alex Sharpe and fiddler Máiréad Nesbitt. The German deluxe edition, released in January 2011, also features newer member Lisa Lambe in the CD.

The tracks on the album are taken from the Songs from the Heart concert, which was filmed in HD at the Powerscourt Estate near Enniskerry in County Wicklow, in 2009. The film of this concert was released originally as a TV special for American broadcaster PBS and later released on DVD to coincide with the release of the album. One of the tracks in the album and DVD, "When You Believe," sung by Chloë Agnew, was also released as a single on iTunes at the same time.

The music videos for each of the tracks authorised for showing in the DVD were released on 27 November 2009 on iTunes for purchase.

Celtic Woman: Songs from the Heart was originally filmed as a PBS TV special and DVD release at the Powerscourt House and Gardens near Enniskerry, County Wicklow, in Summer 2009. The concert was filmed by Alex Coletti Productions and Brennus Productions, with all editing being done by Windmill Lane Post Production in Dublin. Celtic Woman CEO Scott Porter mentioned in the 'making of' featurette that Powerscourt was 'one of the most beautiful and challenging locations we've ever performed in.'

The show, like its predecessor Celtic Woman: A New Journey was delayed by rain before the show; it also rained the day before, 'washing out' the rehearsals and forcing the girls to rehearse inside the main hall in the Powerscourt House. The concert was further delayed when the electrical generator powering the lights, cameras, and other electrical equipment failed during the song "Goodnight My Angel," requiring the show to stop while a second generator was sent for. The first generator was later fixed, allowing the show to continue.
