The Rites of Spring festival or RoSfest is an annual Art-rock/Progressive rock festival taking place at the end of April or in early May.
Established in 2004, the festival was first held at the Colonial Theatre in Phoenixville, Pennsylvania until 2007, and then moved to the Keswick Theatre in Glenside, Pennsylvania for 2008 and 2009. In 2010, the festival moved to the Majestic Theater in Gettysburg, Pennsylvania, and in 2019, the festival moved to its current location at the Sarasota Opera House in Sarasota, Florida.
On December 26, 2020, co-founder George Roldan announced on the official RoSFest Facebook page that RoSfest would end its 16-year run as of 2020. Increasingly expensive production and travel costs, combined with tighter visa restrictions for international artists traveling to the United States, plus financial losses resulting from the cancellation of the 2020 festival due to the COVID-19 pandemic had made continuing the festival unsustainable.
However, on February 1, 2021, Roldan posted a subsequent announcement stating that RoSFest would continue under new management. On February 3, 2021, New management memeber annouanced.  On February 6, 2021 the new management announced that the 17th edition of RoSFest would take place on May 6, 7, and 8, 2022 at the Sarasota Opera House.  On April 18 a new announcement was made that the festival had to be rescheduled to April 15, 16, 17 2022. 
RoSFest was founded in 2004 by George Roldan and Tom Smith. The intent of the promoters was to establish a new international progressive rock festival in the United States. The inaugural three-day festival was held on April 24, 25, and 26, 2004 at the famous Colonial Theatre located in Phoenixville, Pennsylvania. The RoSFest artwork since 2007 has been designed by Ed Unitsky. Through the 2019 festival, 166 different bands will have performed at the Rites of Spring Festival.
