International guitar champion Mark Kroos will perform two benefit concerts in Cape Girardeau next week. Last year, Kroos took first in Guitar Player magazine's International Guitar Superstar Competition. He plays both single-neck and double neck guitars using a tapping technique that involves both hands fretting the strings, instead of the usual one hand. The first concert will be at 7 p.m. Tuesday at the Southeast Missouri State University Baptist Student Center. The second will take place at First Baptist Church at 6:30 p.m. Wednesday. Admission is free, but donations will be given to the Martha and Mary Project.
