"It feels like there's less people this year because of the weather, but it's a lot more crazy, a lot bigger artists coming out here, so I think it's crazy. It's getting bigger every year definitely," said Nely Jackson who is visiting from Dallas.
Rain led to cancellations of several free shows at Auditorium Shores Saturday, but thousands downtown weren't afraid to weather the storm.
"The weather can't stop us. Nothing can stop us, yeah, no, nothing can stop us," said Kara Adkins a New Yorker who said this is her first year at SXSW.
The festival started as a way to bring artists together to develop their careers and share ideas, but has grown into much more than that. Technology, films, and star-studded events draw visitors from all over the world.
"All the people, meeting new people, seeing new stuff, all the knowledge that's going around, it's pretty dope," said Kristen Garth who just moved to Austin from Temple.
For many undiscovered artists, SXSW is still all about the music.
"For me personally, for bands like us who are just starting out it's a really good way to just get your name out there," said Max Goldstein who was in Austin with his band from Chicago.
"It was more of like a promotion thing. It's kind of like fans and artists come together to meet people. You can connect with people, a lot of deejays, a lot of producers," said Jackson.
SXSW started in 1987 with just 700 registrants. This year that grew to 72,000, but all good things must come to an end. Sunday is the last day of SXSW 2015.
"I'm pretty sad. If this could happen all the time it'd be pretty dope," said Garth.
"I'm ready to go home. I'm ready to get back to my city, but it's awesome though. It can't last forever, you know what I mean," said Jackson.
This is the first year Austin police have enforced a "No Refusal" initiative during the festival. Anyone suspected of driving drunk who refuses a breathalyzer will be court-ordered to give blood.
Police said they arrested 17 people overnight Friday for driving while intoxicated. 10 of them had their blood drawn. No refusal ends Sunday at 5 am.
