New Year's Eve

A rooftop at midnight: a countdown to the end of your song, fireworks over the skyline, confetti, champagne and a sparkler greeting in black, gold and silver.

Midnight Countdown

The countdown to the end of your song in large rolling gold numerals over a night skyline whose windows light with the music, fireworks blooming behind; the last ten seconds count down one by one and midnight brings the greeting.

Classic Studio

Skyline Fireworks

A fireworks show over the city and its river: shells launch from the rooftops on the beat, the bass sends them higher, each burst sized by its own part of the spectrum, and a salvo opens every new section.

Classic Studio

Confetti Drop

A faceted ball on a mast above the city, each ring of facets lit by a band, that drops to midnight over the song's final minute through falling gold and silver confetti.

Classic Studio

Champagne Bubbles

Two champagne flutes against a city out of focus, bubbles rising in streams that follow the music, the rims catching the beat; the glasses clink as each new section begins. Calm, for slower songs.

Classic Studio

Clock Face

A gilded clock whose hands meet at twelve at the end of your song, its sixty minute marks a circular spectrum and its second hand kicked by the beat, over the city skyline.

Classic Studio

Sparkler Writing

A sparkler writes your greeting in light across the night, once per section, sparks spraying from the tip with the highs and the beat; the written words glow and slowly cool.
