Phish's improvisation includes a number of "types" among which aficionado fans distinguish. These are in addition to segues (where > and -> are not the same thing), theme-oriented jams around teases, rotation jams, and silent jams:
Pornofunk is the funkified "cow funk" sound that evolved evolved throughout 1997, and particularly on the summer and fall US tours, especially in Also Sprach, Cities, Ghost, Gumbo, and Wolfman's Brother. Though there was an attempt to label this "type III," neither that nor even "pornofunk" was popularized as widely as "Type II" (and, by comparison though not as common, "Type I") This is because many feel that this is not a "type" of jamming, but something closer to a genre (funk), and that Types I and II jamming could occur within various contexts, of which Phish adopts many (rock, jazz, funk, reggae, folk, bluegrass, et al.). Charlie Dirksen posted (11/21/97) the following excursis of examples:
Phish.net is a non-commercial project run by Phish fans and for Phish fans under the auspices of the all-volunteer, non-profit Mockingbird Foundation.
This project serves to compile, preserve, and protect encyclopedic information about Phish and their music.
The Mockingbird Foundation is a non-profit organization founded by Phish fans in 1996 to generate charitable proceeds from the Phish community.
And since we're entirely volunteer – with no office, salaries, or paid staff – administrative costs are less than 2% of revenues! So far, we've distributed over $2 million to support music education for children – hundreds of grants in all 50 states, with more on the way.
