He has collaborated with Youth Music Theatre UK in a new stage production of the play, which is opening at Belfast's Lyric Theatre on Wednesday.
The production showcases a new piece of musical theatre featuring dubstep music combined with live classical instruments and contemporary choreography.
McConaghie has joined forces with director Stuart Harvey to bring the play to Belfast, which features a cast of over 40 young people drawn from all over the UK.
This includes local talent Shannon Cooley, 15, from Belfast, who is cast as a witch, and Kirstyn Kearney, also 15, from Derry-Londonderry, who has been cast as an apparition.
Transporting Macbeth from his Scottish roots to a nameless Asian state sometime in the future, the production centres on the fall of the digital world that sees Macbeth, an ambitious head of security, monitoring groups of young men and women attempting to bring the establishment down.
Composer Garth McConaghie said: "This is an exceptional opportunity for young people from Northern Ireland to develop their musical theatre skills alongside others from all over the UK.
"Our production is particularly exciting as...it allows young people to be involved in the creation and performance of brand new work in front of live audiences, with live classical instruments and urban, electronic music.
"I'm very excited about our production debuting on the best stage in Belfast this summer."
Stuart Harvey added: "It's dark, futuristic, thrilling and enticing, led by a wonderful cast of outstandingly talented young people with cutting edge composition from Garth McConaghie."
