Service Pack Three releases a new single on May 29, marking the second original song from the electronic music project of Greg Bueno.

“Caesium 101” layers vocal samples and dreamy synthesizers over a house beat. The track was written in the third mode of limited transposition first described by French composer Olivier Messaien. The harmonies may feel familiar even if their motions are not.

“Caesium 101” mostly uses presets from Arturia’s emulation of the Casio CZ-101.

The single is available for pre-order on Bandcamp and hits streaming services on May 29.
