Magadog!

The Night Gaunts get slept on a lot. Also great are Streetlight Manifesto, The Suicide Machines, Arrogant Sons of Bitches, Bomb The Music Industry!, Mad Caddies, Simple Minded Symphony, and Faintest Idea.

Despite being a Christian/religious group, Five Iron Frenzy are great.

There’s so many sun genres but I always liked “crack rock-steady” which is more hardcore punk/metal influences. Leftover crack has already been mentioned but No Cash is another good one in that vein. All that’s no horns though.

You mentioned you like Less than Jake so I’m guessing you like the horns and the more bombastic sounds compared to the reggae bass sounds. Only bands like that off the top of my head are Voodoo Glow Skulls. Idk if you can find them anywhere but Link 80 is awesome too. They’re just good, straight up skate punk with some great horns. Old “give them the boot” and “Asian man records” complications would have a lot of different stuff too.

“Ska sucks” by Propaghandi is a must listen song too lol

Ska-P, obviously
