South By Southwest?

I live in Austin, where SxSW is held. It's my understanding you buy a wristband that allows access to the shows and I think you can upgrade (ie spend more) to get even more access. But I think the basic would give you ample opportunities to hear lots of music. The venues are mostly bars around town and you wouldn't need to rent a car--taxis, walking and the new Uber and Lyft services. Downside would be hotels--you might look at Air BnB for more reasonable choices. Weather can be fantastic or cold--flip of the coin that time of year. Good luck!

I'm not sure it is worth buying a wrist band for 'all access.' It gives you
priority but not a guarantee, for access to some of the bigger name shows,
but there is plenty of music available at venues for nothing. Basically,
Austin is invaded by 1/4 million hard-partying people, and if that's your
thing, you might enjoy it. I find it a little overwhelming, but I may be older
than you. Back in the day, it was a place where A&R people from labels
went to hear new bands (and sign them or not). Today, it is a giant branding
festival, with every corner and crevice of town rented out for kiosks, trucks
and 'outreach' by big data, food companies and gizmo makers looking for
eyeballs. Austin is actually more fun at times other than SX, because there
is a vibrant music, art and food scene there 365 days a year, but as long as
you are prepared for a slow motion riot of youth, lines, and a lot of noise to
filter out, you could have a good time (or not). The wrist bands also get you
into various symposia at the Convention Center, discussing everything from
how to market your band to the future of music. Some interesting stuff if
you are selective.
PS: other times to come: ACL Festival; Austin Record Convention (if you
are a vinyl enthusiast).

I have been to SXSW several times, but it was in the first few years of the concept.

It was a magical and wonderful adventure each time. With that being said, you couldn't pay me to go now.

SXSW has become a major commercialized zoo. I agree with Whart. It probably depends on your age and anxiety level.
