There won't be much overhead footage of the crowds and musical acts during this year's South by Southwest festival.

South by Southwest (SXSW) announced in a blog post on Wednesday that it prohibits the use of drones during this year's festivities because of both legal and safety concerns.

"While SXSW may make exceptions to this policy if the drones are used within certain trade show areas where safety measures, such as tethering to the ground are implemented, the airwaves and/or frequency spectrums generally used in the remote control of drones are too congested during the SXSW event to ensure operation safe from interference," the post says.
