Spirit Mother represents the post-grunge era, entwined with Stoner Rock in a way that blurs the line between where one begins and the other ends. On Thistle (Sound of Liberation Records), they touch on a few different sounds from the nineties and bring them into a more modern focus rather than just trying to pay homage to an era. “Violent Son” has a moodier swagger and syncopated riff that finds the guitars adding atmosphere that allows the vocals to coast between it all. The vocals here are in a mellow croon that is possibly drug-induced. The strength of the vocals is not in their range, but in how emotion is conveyed and where he puts his voice.
