Here's what you need to know.
San Mei is heading back to SXSW for a second time this year after playing nine shows in six days at last year's festival.
Here she shares her top tips for surviving SXSW.
1. Be organised! SXSW can be a little hectic at times but if you're prepared, plan your route, check the stage specs, give yourself plenty of time to get to where you need to be, you're gonna have a fun and smooth run.
2. Tighten up your load in/set up. There can be some quick changeovers between bands, so get there early and make sure your setup is as neat and easy as it can be.

3. Stay healthy, hydrated, get sleep, eat well. Jet lag, plus lots of shows can be a challenge on the old bod.
4. Go explore Austin in your spare time, it's such a beautiful city. And if you're a meat eater, find a Salt Lick for some Texas BBQ and you will never be the same.
5. Eat tacos
San Mei is set to drop her new EP, dubbed Cry, on 20 March. Check out her latest single Cherry Days below.
