About When We Were Young 2023
This page documents the 2023 edition of When We Were Young in Las Vegas, United States — the acts that played, in one place, so you can log the ones you saw instead of reconstructing the weekend from memory.
Gigvault counts festivals band by band. A weekend where you caught ten sets is ten concerts in your history, not a single entry called "When We Were Young". Every act you tick lands in your artist history, counts toward your most-seen bands and shows up in your Concert Wrapped — including the ones you caught for twenty minutes on a side stage.
