This fall, Josh Groban will release Hidden Gems, a special collection that brings together ten of his fans' most beloved and rare tracks - many of which have never been available on streaming platforms - along with one brand-new song. Over the years, Josh has released a wide array of deluxe editions, fan exclusives, and special international tracks. Now, these fan favorites have been carefully curated into a single collection that showcases the versatility of his musical journey. The brand-new song, "The Constant" is a stunning collaboration written by Josh and the acclaimed songwriting duo Pasek and Paul (The Greatest Showman, La La Land). It's a beautiful addition to this collection of rare treasures, offering something fresh while honoring the songs fans have cherished for years.
