Barcelona features a book and lyrics by Christine Toy Johnson and music and lyrics by Jason Ma.

Barcelona is described as "a story about the enduring power of love, inspiration and art – and the family ties that bind them. Julianna, an American novelist consumed with guilt over causing the accident that killed her sister Antoinette, receives a necklace from her dead sister in a dream she has about famed architect Antoni Gaudi – and goes to Barcelona to try to discover what it all means. The piece takes the audience on a time traveling journey from Gaudi’s era (1879 and 1926) into 2014."

The CAP 21 Theatre is located on the 5th floor at 18 W. 18th Street, between 5th and 6th Avenues.
