Bruce Springsteen is seemingly gearing up to release another massive collection from his vaults. After teasing on Instagram on Tuesday (April 1) that "what was lost has now been found," The Boss posted the official teaser for what appears to be another career-spanning project on Wednesday (April 2) via another Insta post with the caption #TheLostAlbums.

The Lost Albums" on Thursday, the singer announced on social media Wednesday morning. No further information was provided, but the first volume of "Tracks" was 4-CD, 66-song collection of unreleased material from across his career that was issued in 1998.

After delving into his legendary vault for the first time with the original, 66-song Tracks in 1998, Springsteen began giving specific albums the dedicated rarities-packed boxed set treatment in 2010 with The Promise: The Darkness on the Edge of Town Story. That was followed in 2015 by The Ties That Bind: The River Collection.
