In honor of the new film, Transformers One, coming out next week and upon hearing the soundtrack for it, I decided to make the ULTIMATE Transformers music/theme/soundtrack mashup for every Transformers fan. This mashup includes themes across all the live action films including Transformers 1-3, Age of Extinction, The Last Knight, Rise of the Beasts, Transformers One, and the Transformers Prime television show. Composed by Steve Jablonsky, Brian Tyler, and Jongnic Bontemps. Transformers One Soundtrack used and composed by Brian Tyler. #transformers #transformersone #optimusprime
