The Swedish band Ghost might dress up in black metal-style corpsepaint, but they’ve always been way more of a harmony-heavy arena-rock band in spirit. In recent years, Ghost have become an arena-rock band in practice, too — big enough that Papa Emeritus IV is out here throwing out the first pitch at baseball games. Now Ghost have released a new version of “Spillways,” one of the singles from their 2022 LP Impera, that features guest vocals from Def Leppard frontman and arena-rock king Joe Elliott.
