Tired of playing I-III-V? Stop! That's all you have to do. Try other ideas like I-VII-VI-V, I-VI-V-III, I-II-III-V, anything to break it up. And try just pounding the root note now and then. And listen to "Israelites" and "King Of Ska" by Desmond Dekker. They're like the first two big ska songs from the 60's. Whoever played bass on those songs was really original, and they're 40 years old. Blows away most of those LA punk ska bassists
