What you are listening to is Electronic or perhaps Ambient Classical music, otherwise popularly known as Modern Classical but also supported by a video that uses technology to give life to 19th century scenes from impressionistic paintings. Wow! Atomos was originally commissioned by choreographer Wayne McGregor and premiered at Sadler’s Wells Theatre in London in 2013.

The band are American consisting of two core members, pianist and composer Dustin O’Halloran, a former art student and member of Bella Union band Delvics, he composed the music for Sofia Coppola’s 2005 period drama, Marie Antoinette. Adam Wiltzie is a composer and sound engineer and has worked with Flaming Lips, Mercury Rev, Iron And Wine and Sparklehorse. He composed music for Transformers: Dark Of The Moon and various TV shows. This is their second album and together they make fascinating music that is both striking and seductive.

The piece includes five cellists, viola and two violinists one doubling on harp:

Charlotte Danhier – Cello
Isabelle Klemt – Cello
Nayon Han – Cello
Christelle Heinen – Cello
Arthur Hornig – Cello
Neil Leiter – Viola
Sophie Bayet – Violin
Margaret Hermant – Harp, Violin

Surging soundscapes, subtle rests, long bowed notes, blending Electronic and Ambient sounds with traditionally Classical arrangements and scores. Less edgy and brutal than Philip Glass, more vigour than Harold Budd and compositionally more Arvo Pärt than Eno or Tangerine Dream, this stirring and yet somehow calming modern dance soundtrack is uplifting, stimulating and quietly invigorating. A must for all lovers of Ambient, Electronic and especially Modern Classical music.
