Sparks (Peter Evans and Tom Blancarte) has been playing together since 2005. From the beginning of the formation of the duo, they have been constantly working to push their own boundries of density and speed of interaction while freely improvising. They have performed extensively in New York City and the U.S., and have toured several times in Europe, performing at festivals such as Žedno uho 9 in Zagreb and at the Ring Ring Festival in Belgrade . Since their formation the duo has performed both as a self-contained unit and as a part of larger groups, including performances with Nate Wooley, Peter Brotzmann, Han Bennink and Lisle Ellis. Their first (self-titled) CD was released in 2008 on Creative Sources.

Keeping in the spirit of density of information, Peter and Tom formed the Sparks Orchestra in late 2008. Using graphic scores that utilize the unique Sparks vocabulary, the Sparks Orchestra is a larger realization of hyperactive duo. A smaller ensemble played one performance in 2008; this is the first performance of the full group.
