True Sound of the Underground picks up right where their debut Switchblade Serenade left off. A punishing rhythm section, a piercing crushing guitar and a metal siren behind the microphone is surely doomed for greatness. This band is not doing some kind or retro, retread bullshit; this is a serious testament to the raucous spirit of true heavy metal and Rock n' Roll. Sister Sin is ready to raise some hell... get into it!
