SGBS Trust has been organising concerts in Bangalore for over 50 years. The three main festivals are Gokulashtami, Sharadotsav and Thyagaraja & Purandaradasa Aradhana. In addition, monthly music concerts are held on the first Sunday of every month to promote budding talent. All of these programs are free for the public.
The complete kutcheri schedule is here. The katcheris are being held at the Odukathur Matt, near Ulsoor Lake.
Enjoy!
