Tech and music go together like smartphones and selfies.

And fresh off the first weekend of the Austin City Limits festival comes one of the biggest tech band battle showdowns of the year.

This year, six bands hailing from the offices of local tech companies will compete at the Austin Technology Council’s Battle of the Bands that will also kick off Austin Startup Week Oct. 5th at Mohawk. That’s down from 11 bands that played at the event last year.

This is the third annual Battle of the Bands and each year the event attracts more than 1,000 people, according to event organizers.

The bands are from AthenaHealth, Sailpoint, Under Armour, SpareFoot, Civitas Learning, WP Engine and Dropbox.

The event is free but ATC does want everyone to register for a ticket. There’s also an option to order food from onsite food trucks via Foodee for a few dollars extra.

The fifth annual Austin Startup Week runs Monday through Friday. Check out the full lineup of events here.
