Day 2 gives promoter hope show will be an annual event By Mark Armstrong The Desert Sun INDIO True to its billing as a festival incapable of musical pigeonholing, the first-ever Coachella Valley Music and Arts Festival ended Sunday with a decidedly more raucous flavor drawing more than 30,000 people to the concert's main stage for a finale featuring hard-rock acts Rage Against the Machine and Tool. [...] if the final two hours of last night's show went as smoothly as the previous 46, promoters and local officials were hopeful that the festival will become an annual showcase of eclectic arts and music for Indio.
