Employing a hard-hitting blend of post-grunge, modern rock, and alternative metal, Tantric emerged in 1998 and released its gold-selling eponymous debut in 2001. Featuring three-quarters of the original line-up of hitmaking post-grunge outfit Days of the New, the band released a string of Billboard-charting albums and hit singles as the decade progressed. Like its mother band, Tantric also fell victim to personnel changes, and in 2007, co-founder and vocalist Hugo Ferreira entirely restaffed the group and has remained the sole constant member ever since. Subsequent efforts like 37 Channels (2013) and Mercury Retrograde (2018) continued to populate the hard rock charts.
