The festival features a main stage, second stage,
food trucks,
beer garden, and Dillo Village that hosts art from students and
Chicago-area artists, as well as various other games and activities. Dillo Day is open to all Northwestern University students, faculty, and staff. Students are each permitted to bring one additional guest, and a limited number of tickets are reserved for purchase by
Evanston residents and Northwestern alumni. The second stage is curated in partnership with an additional campus organization-- currently Northwestern's Black student alliance, For Members Only, who has provided Dillo Day with a historic all-Black lineup on the stage for the past 3 years. In addition to Dillo Day, beginning in 2016, Mayfest Productions hosted annual Battle of the Bands and eventually Battle of the DJs competitions in the weeks leading up to the festival. The winners of these respective events perform on the main stage of Dillo Day that year. On May 30, 2020, Mayfest Productions hosted Digital Dillo, a virtual replacement for the annual music festival due to the
COVID-19 pandemic. Those within the Northwestern community received a link to a livestream where they could watch live artist performances and participate in Q&A sessions with them. The following year, Dillo Day was held as a hybrid festival. This once again featured virtual artist performances and live Q&A's, but also had in-person components across campus the entire week of the festival similar to the original Mayfest. This included Mayfeast, a collection of food trucks outside
Deering Library; Mayfit, a thrift shopping event at
Norris University Center; Dildo Day, a variety of sex/body positivity events; student art installations on the Lakefill where the festival is traditionally held; a
silent disco outside Norris featuring Chicago area DJ's; and screenings of artist performances on and off-campus. == Past lineups ==
