Jam Bands: A History
The Grateful Dead
This goes into detail about the history of Jam Bands. By definition a Jam Band is a band that incorporates many genres of music such as rock, folk, blues, jazz, and most importantly improvisation. The Grateful Dead were the pioneers of Jam Bands. For nearly 30 years the Dead conquered by jamming throughout the United States followed closely by their fans, the Dead Heads. By the 1990's, the Grateful Dead had stopped touring and their fan base had largely turned to a band called Phish. Phish toured for nearly 20 years, until retiring in 2004. Now, there are numerous Jam Bands all with their own unique style.
