There is a straight English Dub of Megazone 2-3 and Magazone 2-3 part 2 from the 80's. I have both. Both produced by Carl Macek's Streamline Pictures, rather than Harmony Gold. Macek also produced the terrible 1989 "Akira" dub.
Robotech: the Movie isn't a straight dub of Megazone as it also integrated footage from Super Dimensional Cavalry Southern Cross, and had an entirely different plot. Other than the names "EVE" and "B. D." there is about zero narrative overlap. It's a bit like comparing "Kung Pao: Enter the Fist," to "Tiger and Crane Fists."
Robotech is often excoriated, but, on its own its narrative is quite solid, and expanded beyond the roots of its component series. The novels remain the best iteration of the story as Brian Daley and James Lucento worked with Carl Macek to greatly expand the fictional world. They incorporated much material from the unproduced sequels ("Sentinels," and "Odyssey") to finish out the saga. Spoiler - Gene altered Zor Clone "Rem," and Minmei end up back in the past. Their child is the original Zor, and the songs Minmei sang to him as a child moved Zor greatly, which is why he implanted a susceptibility to music as a "backdoor" to Zentradi conditioning into their programming when the Robotech Masters converted the Zentradi clones from miner to warrior. It gets complex as any 3000-page narrative does.
The Megazone music Fred linked is from Megazone pt 2. The EVE vocalist in pt 2 is superior to pt 1.
"Saved by Science," and "The Future is Now," are not Michael Bradley's best. He's discussed how he had three days to do those songs, as well as the additional music for "Robotech: the Movie." He had a couple months when working on the series Robotech.
Robotech's "Lonely Soldier Boy," is a genuinely solid song, both in the original TV version.
And Michael's 2007 CD with a nice extention of the center bridge.
"Look Up! (The Sky is Falling)" is another solid song, both in its TV version.
And the 2007 CD. The CD has a better music bed, but the 1983 vocals were better. Michael is a little TOO controlled on the CD
Amazingly, I can't find the 2007 CD version of" Look Up!" on YouTube!
Fred, this is for you - there's an Argentinian artist named Matais d'Andrea who does metal covers of songs from 80's cartoons including Robotech and Thundercats, and he did a ridiculously incredible version of "We Will Win," from Robotech which proves that is an incredible song just slaughtered by Reba West in the show.
And his cover of "Look Up!" which, again, proves how just GOOD the song could be with a better music bed.
