This is so not metal, there's not even any guitar, but I just checked these guys out tonight, and it's just flat out awesome. They're pretty pop-sounding, they seem to cover a lot of pop songs, maybe exclusively for all I know, but to say cover is understating it. They completely rework them, and bring in a lot of modern jazz/fusion and funk elements in. And they've got absolutely monster chops. The bassist looks like he'd be in Blink 182 or something, but he's insanely good.
The end of that last song is just fucking dynamite. Anyway, figured some of the bass dudes here might dig these, maybe a few others, too.
