Purists will be pained to know that I find the 90125 album fantastic.
Nothing wrong with that! I love 90125. The next album Big Generator, is my second favorite. Tales From Topographic being my absolute favorite. Big Generator had Trevor Rabin conciously bring back some of the 70's melodic guitar, but still kept the heavy rhythm.
And Yes, Drama is a great album. The keyboard, guitar, and bass interplay in the middle of Machine Messiah is fantastic. Squire gets the bass galloping along in that song. Some of the material that's on Drama was material Jon and Rick wrote before they had a hissy-fit and quit the band. I have a bootleg (got in back in '87) cassette of those studio outtakes. Now some of it made it onto the remastered Drama album. I think Trevor Horn reworked some of the Anderson songs, and made them better. He's not as good as the cosmic/strange JA, but reworking those songs made them work for the album direction. Tempus Fugit and Does It Really Happen are strong songs as well.
Pretty much as Genesis, the majority will say any Yes album from '71-'77 is the band in their prime. Tormato ('78) had some good songs, such as Silent Wings of Freedom, Onward, Release-Release, and Future Times. But, the band members were all kind of losing enthusiasm in Jon's lyrics, and band direction, so the album had some half-ass, lackluster songs.
I think the '93 album Talk is a strong album. There's actually a great 17+ minute song called Endless Dream. Trevor's got some slide-like guitar in the song that's reminiscent of Relayer, and CTTE albums.
