Want to feel old? The Used is on its 15th anniversary tour. Yep, the seminal Utah screamo band is working on two decades of emotive rocking together. And while their raw style brought them into the alt spotlight in the early aughts,  it’s the band’s ability to evolve to a softer, more refined sound without losing their edge—along with legions of die-hard fans—that has kept them relevant. Whether you angry-cried in your room to their emotionally honest lyrics as an angsty teen or recently discovered the emo titans via their just-dropped acoustic album, you’ll want to scream along when they hit town for back-to-back shows on May 6 and 7 at the House of Blues. / Gracie Dietshe 

The Used play May 6 + 7 at the House of Blues, 15 Lansdowne St., Boston. $33-$43. livenation.com.
