Over at DimeADozen, Survivor69 said:
"Stefano Bollani and his Danish Trio were announced as openers for the "Il Cartellone - Radio3 In Festival", but they cancelled last minute because stuck in Iceland or somewhere over there due to volcano ashes; so their place was taken by Guerrini's cohorts, for a lively and modern jazz set, with a hint of Zappa, coming out not just beacuse of the marimba"
And that was reason enough for me to check out.
CIRKO GUERRINI performs instrumental, modern jazz, with lots of room for improvisations. And yes, Survivor 69 is very right. There are a lot of interfaces with Zappa's music.
The ensemble has one CD out on the Giotto Music label.
