Info
Voces de Profundis was inspired by the Hitchcock film Psycho. The composer, Stepan Rak, uses the guitar's widest possible vocabulary of effects here and even uses a spoon to produce ethereal sounds from the strings. Other devices include scraping the strings with finger nails, passages in harmonics, trills high on the fingerboard, partial pressure chords where the fingers barely hold down the strings as well as many other special effects. The result is an exciting piece of music that is modern yet is held together as a unified whole. Interestingly, this version of Voces Profundis, here played by Vladimir Mikulka, is only 12 minutes long, whereas, the original played by Stepan Rak, is 17 minutes in length.
