Roxanne has represented several clients in the area of performing arts including being the lead negotiator on a landmark development agreement with Goldenvoice, LLC, the promoters and owners of the world’s largest and most famous music festival franchises, the Coachella Valley Music and Arts Festival and Stagecoach, which take place in the City of Indio every spring. The development agreement ensures that the Coachella and Stagecoach festivals stay in the City of Indio through 2030 and allows Goldenvoice the ability to expand from its current three-festival format to a total of five festivals each year, which it did so with the successful Desert Trip concert event.  Roxanne assisted the City of Indio in securing a guaranteed per-ticket fee, which provides much needed revenue to the city, as well as a related reimbursement agreement to ensure the festivals are cost-neutral to the city.  In addition, the firm assisted in the preparation and review of a thousand-plus-page unusual environmental impact report that evaluated the environmental effects of “music.”
