What Aspen shows
Aspen sets the camera at the foot of an aspen grove, looking up at the sky. White trunks rise toward the light, and thousands of leaves on their twigs flutter, flip over and change colour.
The wind follows the music: a light breeze in the verses, gusts in the choruses, and sunbeams breaking through the leaves. A calm world for folk, acoustic, indie and lazy afternoons at home.
