Much like its next of kin (alternative country-rock), Americana developed during the 1990s as a roots-oriented reaction to the slick commercial sounds that dominated mainstream country during the decade. But while alternative country-rock developed out of punk, alternative rock, and country itself, Americana sprung from less raw and edgy source material. In fact, much of what fell under the Americana umbrella was in fact a revival of dormant country styles, including Western swing and rockabilly. Though considered an alternative radio format, Americana did not break with country tradition; instead, it embraced it — something, ironically enough, that the music hitting the Nashville charts throughout the era did not do.
