on september 12, 2004, dmb played their second benefit show in less than a year, with a free show at golden gate park in san francisco. this concert drew one of their largest crowds and produced a popular bootleg. the band was joined by guitarist carlos santana on many songs, and the tracks led to the second release in the live trax series, "live trax vol. 2" released on december 17, 2004. the album gave fans previews of newly penned songs "joy ride", "hello again", and "sugar will". however, only "hello again" was actually included on the subsequent album release, "stand up".
