First launched in 1999, Epitonic was a source for independent music across multiple genres from both signed and unsigned artists.

Epitonic was an iconic part of the music industry as it found its digital roots in the 1990s and hosted tracks from indie artists like Animal Collective, Built to Spill, Burd Early, Dismemberment Plan, as well as mellow, melodic instrumental bands such as Pele, Dianogah, and Six Parts Seven.

Electronic music was also one of the most popular genres on the site, representing artists such as Bent Halos, Delerium, Carl Cox, and BT.

In 2010, after six years of inactivity, original co-founder Justin Sinkovich announced that he would be relaunching Epitonic as manager and principal owner.

In alphabetical order, the bands who provided exclusive tracks are: All Smiles, Autumn Owls, Bloodiest, Braids, Cast Spells, Closed Sessions: ATX featuring Esso and Scheme, Marissa Nadler, Restorations, STRFKR, Withered Hand, and The Wrens.
