Just the fact of finding on your way a quartet like Sigma could make you think about a new approach to the word quartet and what meaning it has in the history of music and in the future. We are talking about an instrument, the quartet, homogeneous, composed of four integrated individualities that form in themselves a sonority of an expressive power at the level of the great string quartets, with a technical capacity that aims to go beyond the established limits and with the illusion of the one who experiences for the first time extreme sensations. This is Sigma.
