Some guesses for long beach that might fit: four year strong, august burns red, la dispute, poison the well.
Looks like Streetlight Manifesto could fit next to State Champs on LB’s poster. But that seems to optimistic at this point
I’ll add a few guesses too: Hawthorne Heights, Lagwagon, Letter Kills, Less than Jake,The Amity Affliction, The Aquabats,
I was also thinking about them but wasn't sure if their name was too long for the space but they would be a sweet addition, I saw them a long time ago at the catalyst in santa cruz
Strung Out, Stick To Your Guns, or Street Drum Corps (since Frank will already be there) are my guesses.
That Bad Religion/Dropkick Murphys tour is skipping Southern California, and is in Nevada/California during that time period. I think they both get added to LB. Both fit
The spot next to better lovers seems too big for bad religion but dkm seems to fit perfectly next to drain
Theres almost no way a known band will play California and skip southern California. Edit: oops meant to write this on the other thread. I think theres a decent chance Bad Religion and Dropkick Murphys is on this.
