Here are a few...
Chicago - "Hard Habit to Break", "Stay the Night", & others on the "Chicago 17" album
Howard Jones - "Things Can Only Get Better" on the "Dream Into Action" album.
Toto - "Africa" & others on the "Toto IV" album.
U2 - Various songs on the "Joshua Tree" album (I believe Brian Eno played keys on this album)
Someone earlier mentioned Don Henley's outstanding "Sunset Grill" (love that song). Do you KNOW that the synth horn and synth guitar solos were made with a DX7? I don't want to say that they're not, because they *might* be, but they sure don't sound like a typical DX7 patch.
An amusing DX7 related story...
I was talking to Chicago keyboardist Robert Lamm just prior to a 1984 concert in Louisiana. The DX7 was of course all the rage at that time, so our conversation naturally drifted in that direction. Now at that point in time, I owned a single DX7, but they had already become hard to find because of their huge popularity. Talking about the DX7, Lamm said, "...Yeah, we only have four of them."
I didn't say it, but all I could think was, "Jeez! FOUR DX7's!!! I only managed ONE, and I wouldn't even know what to do with FOUR!"
In addition to their four DX7's, I remember that Bill Champlin - who was brand new to Chicago at the time - also had a Yamaha GS2 in his rig (the GS1 and GS2 were pre-DX7 FM synths).
In the years following 1984, both Robert Lamm and Bill Champlin toured with identical rigs that consisted of (among other things) a DX7 and KX88 on an Invisible Support keyboard stand, plus a TX816. Jimmy Pankow (trombone player) also had a DX7 on stage, which he had humorously re-labeled "DX7000 Turbo".
I still own my original DX7/E!, along with a TX216, a DX7IIFD/E!, and an FS1R. More FM than anyone needs!
