Whether The Beatles really loved bugs, or if Aussie rockers AC/DC had a thing for electric currents could make for great trivia in a bar. As for Shanka Tribe, the Kozhikode-based band that’s causing all the buzz in the music world right now, they like to stay true to their name.

Every performance of the tribal techno collective begins with the call of the conch (shanka) — a traditional invitation to listeners. The call will echo in Mumbai this weekend at a pre-event showcase leading up to the Echoes of Earth Festival in Bengaluru in December.
