Music that penetrates the soul.

Their albums are released through Vitamin Records and primarily performed by astring quartet, though other instruments have been used.

Their albums honor a wide variety of genres, including pop and rock, metal, techno, country, and hip-hop, and a wide variety of groups, such as Simple Plan, Queen, Led Zeppelin, Michael Jackson, The Beatles, Black Sabbath, Iron Maiden, Bruce Springsteen, Jimi Hendrix, The Smashing Pumpkins, Radiohead, System of a Down, The Killers, Red Hot Chili Peppers, Coldplay, Muse, Thirty Seconds to Mars, Slayer, Adele, Lady Gaga and many more.

The group began in 1999 "as an experiment in transforming rock songs with classical instruments." It later expanded to include a variety of popular music.
