About Efficsounds

Hello and thank you for dropping by!  My name is Aaron O’Donnell and I am a guitarist, music producer, composer and the founder of Efficsounds.

Writing music and playing the guitar is my passion.

After years of writing riffs to turn into songs for my band…

I now write music for Royalty Free Libraries for Content Creators to use in their projects.

The aim now is to help as many others as possible to also write Badass Rock and Metal Music they can share online.

Enjoy, and please feel free to drop me a line.

You’ve got this my friend!
