The Cowsills are the original family band. Formed in Rhode Island, the group started out with a trio of brothers: Bill, Bob & Barry, but eventually grew to include brothers John and Paul, sister Susan and mother Barbara. They had big hits with “The Rain, the Park and Other Things,” “Indian Lake,” and “Hair.”

The Cowsills were the inspiration for the hit TV series The Partridge Family. Then, years later, the group got their own documentary, “Family Band,” which is available on streaming services.

At a time when division is at an all-time high, we need some of that familial harmony once again to bring us together. The Cowsills have regrouped for their first new studio album in almost 30 years, called Rhythm of the World, from Omnivore Recordings.

We talk with founding member Bob Cowsill on how he, brother Paul and sister Susan, put this new album project together, with the trio of them writing the bulk of the songs. He reveals how one song was inspired by a saying from Howard Kaylan of the Turtles, another was written about how Hurricane Katrina affected their family.
