An a cappella musical group from Marist College in Poughkeepsie visited North Warren on Friday as part of the Arts in Education program, although the fact that North Warren alumni Poul Carstensen is a member of the group was how the visit came about. Weve been talking about coming here with the group for a year or so, Carstensen said. It just finally came together. Carstensen has been singing in school events throughout his career, and was involved with school plays at North Warren. Ten of the 11 members of Time Check held a workshop with senior choir students, discussing a cappella singing, breathing, articulation and other musical subjects. We practice about four and a half hours a week, said Time Check member Eddie Storey from Long Island. Were also in the mens choir, chamber singers and other groups. The purpose of the visit, Storey said, was to have fun and entertain. And embarrass Poul as much as possible, he added. The singers had varying majors, with three of them, including Carstensen, majoring in communications. Others were studying education, psychology and business. We say major in what youre going to do for the rest of your life, and minor in your passion, Storey said. Five of the 11 members have minors in music. Time Check sings in collegiate a cappella competitions as well as singing the Star Spangled Banner at college athletic events and even does wedding receptions. Theyve made radio appearances and put out a CD every two years. After the workshop, Time Check members spent time with 16 musical students, teaching them In the Still of the Night, as part of an a cappella concert that afternoon.
