Ring Mining unites a psychedelic dream team comprising Brooklynites Heavy Winged and Portland's Inca Ore. On the first side its down to the epic fudge-filled grooves of Heavy Winged to dominate the horizon, blistering through their hallmark freeform avant-metal with an extra fathom or two of depth supplied by the wandering ambience of Inca Ore's toils. Flipping over, Ms. Ore takes to the mic - and it's as if Heavy Winged suddenly turn into a fully fledged rock combo with an actual lead singer. It's all a bit of a blur though, and the vocals dissolve into the band's low-slung riffing and cataclysmic bass rumble in a predictably abstract fashion.
