Remember “Ocean Avenue,” Yellowcard’s inescapable, breezy 2003 hit, brimming with hazy scenes of Southern California sunsets and nostalgia for young romance? Even for those who don’t quite look at lost love through rose-tinted lenses, the track hits a sweet spot somewhere between solemn and sunny (with a twist of violin). Florida-bred pop-punk heavy hitters Yellowcard have occupied the space between bright and dark and dominated emo playlists for nearly 15 years. If you’ve ever wanted to belt out “Only One” with someone you love, now’s your chance — and it’s among your last, as the band wrap up what they’re saying will be their final tour at the end of March. Also Sunday, March 19, and Friday, March 24, at the Novo and Saturday, March 25, at House of Blues Anaheim.
