2020 sounds like a good year to make a comeback. Realistically, I see them getting a new frontman with metal roots. Not to replace Chester, but to definitely continue making music they love for fans. And I'm sure they will repeat that a million times during their comeback.
I see them going with a younger frontman. They have a HUGE catalog with music they just can't ignore. Fans want a heavy as fuck A Place For My Head. A killer One Step Closer. A bat shit crazy Faint. You won't be able to do that if you don't have someone who's ready to rip the fucking ceiling off of your god damn house. I feel a younger metal based frontman is needed because as the other guys are getting older, you won't find many guys in their late 40s and up, years from now screaming their heads off. A younger frontman will give LP more longevity.
And keep in mind guys, as much as we adore the fuck fuck out of Chester, he had an amazing range. His voice is iconic. You wont find anyone that can do both, sing and scream like he can. But you can definitely find better singers. Or better screamers out there.
Bring on the fresh, young, sexy, metal screamer meat please.. And slap that shit in my face.
