Whiteside was commissioned in 2016 by Lorimer Productions to compose Nobilis Humilis inspired by the hymn to St Magnus, "Nobilis, humilis" for Cappella Nova's Echoes and Traces tour.[16] The same year he was commissioned by Cottier Chamber Project to compose a piece based on the work of Lord Kelvin and John Stewart Bell for Juice Vocal Ensemble, Glasgow University Chapel Choir and Davur Juul Magnussen trombone ensemble for performance in the University of Glasgow Cloisters. The resulting piece was called Always Ever Unknowable[2] with words written by Danish Playwright Helene Grøn. He also attended Magnetic North's Rough Mix residency in Aberdeen.[17]
In 2017, Whiteside was commissioned by Scottish Opera to again collaborate with Helene Grøn for a short opera for Scottish Opera Connect called Little Black Lies.[18] He was also accepted onto the RTÉ NSO/CMC composer lab to write Repercussive[19] and commissioned by the Institute of Physics for the NI Science Festival to collaborate with Marisa Zanotti on writing Entangled for string quartet, electronics and film based on the work of John Stewart Bell for and premièred at the NI Science Festival 2018 by the Aurea Quartet.[4] This work was also featured on his second album Entangled release in October 2019. He also scored David Graham Scott's The End of the Game[20] and was supported by Creative Scotland to attended the Atelier for Young Festival and Cultural Managers in Shanghai run by the European Festivals Association.[21]
