I still think it's Korn but there are some smaller headliner options around:
- Falling In Reverse (honestly, I hope it's not them - would be such a risky move)
- Rise Against
- Bullet For My Valentine (bit of a stretch, would feel incredibly unbalanced)
In fact, Porto's line up is better than Barcelona's, if you take the whole into account. Much more concise and aligned with primavera atmosphere.
