Eric Whitacre... is an American composer of choral, wind and electronic music. He has served as a guest conductor for ensembles throughout Europe, Asia, Australia and the Americas. He is one of the most popular and performed composers of his generation, his works being part of standard choral and symphonic repertoire. He is inspired by pop and electronic music and is known for his work with virtual choirs—creating choral community via the internet.Even if you don't like choral music, you should watch a couple minutes of this video to see what can be done with webcams, microphones, and a healthy dollop of imagination.
Addendum: The soundtrack of the video I posted above this one sounded familiar, and with a quick search I discovered that I had posted the musical arrangement back in 2010. I think it's worth a repost now.
And here's the wiki on "Lux Aurumque" -
Lux Aurumque ("Light and Gold", sometimes "Light of Gold") is a choral composition in one movement by Eric Whitacre. It is a Christmas piece based on a Latin poem of the same name, which translates as "Light, warm and heavy as pure gold, and the angels sing softly to the new born baby". In 2000, Whitacre set a short Latin text for mixed choir a cappella. In 2005, he wrote an arrangement for wind ensemble. The choral version became known through Whitacre's project Virtual Choir in 2009. The piece is also available for men's choir. Its duration is about four minutes.
