In a clear sign that they are ready to embrace the future with open arms, the Boston Symphony Orchestra has not only launched an extensive App but has also introduced new "Casual Fridays", as well -- in the hopes of attracting a more youthful cliental. In addition to lowering ticket prices to between $25-$45 for one Friday a month over the next three months, the BSO will be passing out 110 iPads to audience members in designated areas of the venue to provide a more interactive experience for tee-shirt and blue jeans concert goers.
