Ruder's debut album 'Rerajahan’, a journey into dualisms on a quest for balance.

Yantra (or Rerajahan in the Balinese culture and Sanskrit word for ‘a machine’) is a representation of the Tantric traditions of the Hinduism religions, used to worship deities and to gain benefits from their supposed occult powers. Its geometrical pattern changes the vibrations of the space it is placed in, altering frequencies.
On a view of the universe as a correlation of sound and frequencies, wavelengths have compression and rarefaction, representing dualities in our existence.
