"Mercy" begins with an improvisation on the composition "River Flows In You" by the South Korean pianist Yiruma. The British composer Max Richter, whose habitual field of operations is the electronic, ambient and film score scene, contributes the title track "Mercy". A quiet, almost meditative work for piano and violin, it is framed by congenial segments with works by Arvo Pärt and Johann Sebastian Bach.

"This project gave me the chance to give my imagination free rein and translate earlier experiments on the concert platform into the environment of the recording studio. This makes it a highly personal choice, contrasting the mathematical, technical side of the pieces with a nuanced rhythm sensed on stage. I thought about what I would like to hear on disc myself, taking into account the reaction of my audience."

Long-time friends and associates – like the Italian electronic music artist Giordano Franchetti, who created a sound synthesis with NASA "space sounds", or pianist Friedrich Wengler, whom Widjaja has known since his schooldays – accompany him on his new album. The greatest challenge proved to be the piece "Eneril" (inspired by J.S. Bach's plea for mercy "Erbarme Dich"), in which the vocal part was taken by Mongolian singer Urna Chahar-Tugchi, who grew up in a shepherd family in the grasslands of Ordos. "We took a risk, because Urna has a totally different approach to classical music and in any case she does not work with musical notation." The result is a track that is Iskandar Widjaja all over: wandering between worlds, never without a homeland, being at home everywhere.

The release of "Mercy" on the Berlin Neue Meister label lays the foundation for an international concert tour in the late summer and fall of 2018.
