SISTER SIN in April 2009 made a new song, "Beat 'Em Down", available for free download via MySpace page. The track was recorded as a tribute to the late great Gothenburg boxing champ Ingemar "Ingo" Johansson, who passed away in January 2009. "Switchblade Serenades" debuted at No. 107 on the Top New Artist Albums (Heatseekers) chart, which lists the best-selling albums by new and developing artists, defined as those who have never appeared in the Top 100 of The Billboard 200.
