"Hearts Of Cold", the new video from Swedish female-fronted heavy rockers SISTER SIN, can be seen below. The clip was directed by Eric Richter in Chicago, Illinois and "packs a ferocious punch in a span of four minutes and sixteen seconds that will have your adrenaline rushing with your fist held high," according to a press release. The song is loosely based on characters Mikey and Mallory from the 1994 movie "Natural Born Killers" and mirrors the Finnish, real-life version of them — Juha Veikko Valjakkala and Marita Routalammi — who crossed the border over to Sweden and killed a family of three."Hearts Of Cold" comes off SISTER SIN's third album, "Now And Forever", which entered the official chart in the band's home country at position No. 44. Released on October 23, 2012 via Victory Records, the CD was recorded at Standstraight Studios in Stockholm with producer Chris Snyder and was mixed by Cameron Webb (MOTÖRHEAD, SOCIAL DISTORTION, DANZIG). SISTER SIN singer Liv Jagrell underwent surgery in November to remove nodules on her vocal cords. As a result, the band was forced to cancel all of its previously announced shows for the remainder of 2012.
