Introducing: Sister Crystals - For So Long

Formerly known as Magic City, the Chicago four piece - who now go by the name of Sister Crystals - are back after a period away with new track "For So Long", and they're sounding mightily impressive to boot.

Now clearly embracing their psychedelic tendencies, the big guns are certainly out here, as the song grows in stature, perfectly placing Lauren Whitacre's delicate vocals over the thrashing guitars. There's a sense of confidence that has obviously come with 18 months of pre-planning.

The track is yours for free over here, with an eagerly anticipated LP due in the spring.
