JamBase

JamBase is an online database and news portal of live music and festivals with a focus on jam bands. It was founded by Andy Gadiel and Ted Kartzman in 1998. The website primarily acts as a service, providing a public API that concert promoters and venues use to publish concert data to the site. The data is also used by third-party developers for other products. In addition to raw data, the website includes a news section publishing information about concerts in a blog format.
