Christmas Lights

Six secular scenes of one snowy night: a lit pine, swagged garlands, glass baubles, a snow globe holding your cover, icicle lights and a cozy window, with every bulb on its own band and the chase stepping on the beat.

Tree Lights

A snow-dusted pine wound with string lights: each bulb is a band from the bass at the base to the treble at the tip, every beat steps the chase one bulb, the bass warms the baubles and a new section lights the star.

Classic Studio

Garland Chase

Fir garland swagged across a snowy night with velvet bows; the bulbs run the spectrum left to right and every beat chases the light one bulb along.

Classic Studio

Bauble Reflections

Glass baubles hang over a field of soft tree lights: the spectrum shines in their reflections, the bass glows inside them and each beat sets the front one swinging.

Classic Studio

Snow Globe

Your cover inside a snow globe on a lit base: every beat shakes the snow, the base lights carry the spectrum and the globe shines in a glossy table.

Classic Studio

Winter Frost

Icy icicle lights along a snowy eave over a moonlit, frosted forest: each strand is a band, each beat drips light down the next strand and frost creeps in as the song plays.

Classic Studio

Cozy Window

A warm window on a snowy night, framed in string lights with candles on the sill: the lights follow the music gently, calm enough for talk and spoken word.
