German metal legends Accept announced Friday a pair of surprise US tour stops leading up to their upcoming South American tour. The band will perform in Sioux Falls, South Dakota on March 3rd and in St. Charles, Illinois on March 5th. Founding Accept guitarist and principle songwriter Wolf Hoffmann noted that the band had planned to take some time off to begin writing their next album, but decided to schedule the two shows to keep the band sharp. The band still has the next few weeks and just under a month after the US tours before heading to Europe for a show in Austria on April 6th. Then the band heads to Buenos Aires, Argentina on April 6th to begin a 9-day, six-stop South American run. Click Here for the dates and venues.
