Inside A Dream follows the departure of guitarist and oldest brother Jamie Sierota from the band, comprised of all siblings. Vocalist Sydney Sierota explains, “That literally forced us on a journey of having to discover this sound. We still had electric guitars, but they weren't the center of the music anymore.”

The album trades guitar-centered alt-pop songs for a more mature sound with vintage synths and drum machines, which are present on their new single.

Listen to “Goodbye” here:

In addition to the album announcement, Echosmith also announced that they will be kicking off a 6-week tour North American tour on October 5, in Kansas City, Missouri. Tickets go on sale today, July 14.
