Funk is a major element of certain artists identified with the jam band scene of the late 1990s and 2000s. In the late 1990s, the band Phish developed a live sound called "cow funk" (aka "space funk"), which consisted of extended danceable deep bass grooves, and often emphasized heavy "wah" pedal and other psychedelic effects from the guitar player and layered Clavinet from the keyboard player. Phish began playing funkier jams in their sets around 1996, and 1998's "The Story of the Ghost" was heavily influenced by funk. While Phish's funk was traditional in the sense that it often accented beat 1 of the 4/4 time signature, it was also highly exploratory and involved building jams towards energetic peaks before transitioning into highly composed progressive rock and roll.
