After several years of rumors, the long-awaited follow-up to Bruce Springsteen’s 1998 Tracks box set is upon us with the release of Tracks II: The Lost Albums on June 27.

Even during the gap years between official releases, The Boss was always working on songs and recording, be it a hotel room in Los Angeles or in the studio inside his sprawling home in Colts Neck, N.J. These seven albums presented on this highly anticipated collection, in many ways, provide a portal into those moments when it seemed like Springsteen was radio silent. In fact, he was anything but, working up material that would remain in his vault until now.

“The seven albums presented here have for one reason or another never seen the light of day,” Springsteen wrote in the introductory note that accompanies the box set. “After recording, mixing and reviewing them I felt I’d found faults that made me unsure of turning them into major releases. I’ve always released my records with great care, making sure my narratives built upon one another. I’m glad I did, as it usually assured the best of what I had came out, weaving a clear picture in my fans’ minds of who I was and where I was going in my work life at that moment.”

Recorded between 1983 and 2018, these seven albums each provide revelatory insights into the moments between the eras. This is Springsteen unfiltered, working through ideas without the pressure of a timetable or expectations from his longtime label Columbia Records. Some are fully realized visions that nearly got released, such as the loop-heavy 1993 Streets of Philadelphia Sessions, while others are works in progress that were shelved to focus on other endeavors including 2005’s Faithless, the soundtrack to a “spiritual Western” that was never made.

At 83 songs (including 74 never-before-heard numbers), Tracks II: The Lost Albums is teeming with material longtime fans have been waiting to hear since whispers of this box set began floating in the air sometime in the last 10 years or so. And now that it’s finally come to fruition, we look at one song from each LP you should check out first upon diving into this unprecedented collection.
