Massachusetts metallers KILLSWITCH ENGAGE have released the following statement:"KILLSWITCH ENGAGE will, unfortunately, have to postpone their upcoming South America tour due to the illness of lead singer Howard Jones. Howard is currently bed-ridden with a gallstone issue and has been told by his doctor that he should not leave his bed until further notice. He is currently getting proper medical care and hopes to be on his feet and in less pain by the end of the week, at which time we will determine how soon we can reschedule these South America dates. "KILLSWITCH would like to apologize to their fans in South America for this setback and want to assure them that the band has every intention to make up these dates in the near future." The new, self-titled album from KILLSWITCH ENGAGE sold 58,000 copies in the United States in its first week of release to debut at position No. 7 on The Billboard 200 chart. The CD was released on June 30 via Roadrunner Records. It was produced by Brendan O'Brien (AC/DC, RAGE AGAINST THE MACHINE) and co-produced by guitarist Adam Dutkiewicz.
