This video has some text that explains the situation (it starts at about 1:10).
Your donation will go to the band regardless of whether they make their goal (unlike Kickstarter, which is a bit more like a challenge grant). The reason to do it through IndieGoGo is for the usual assortment of goodies — in this case, an unreleased live recording and your pick of free CDs. There’s also a drum lesson up for offer, although it looks like no one’s taken Anderson up on it yet.
I’ve written before about his Hard-Boiled Wonderland album, which struck me as more improvisation-based or at least very loose in defining musicians’ parts. Touch and Go’s music is more about Anderson’s jazz compositions. There’s more info and a brief interview with Anderson on the Porto Franco blog.
The band consists of musicians who are great bandleaders in their own right: Ben Goldberg (clarinet), Lisa Mezzacappa (bass), Darren Johnston (trumpet), Aaron Bennett (sax), and Sheldon Brown (clarinet). It’s like an all-star team being sent to Novara, enjoying an international stage for showing off Bay Area jazz. Best of luck to them.
