Yes, "Shock to the System" from Union (1991): YESterdays

Yes, “Shock to the System” from Union (1991): YESterdays

“Shock to the System” almost seems like a leftover from Yes’ ‘Big Generator’ era, instead of a tune begun by Anderson Bruford Wakeman Howe.

Yes, "I Would Have Waited Forever" from Union (1991): YESterdays

Yes, “I Would Have Waited Forever” from Union (1991): YESterdays

“I Would Have Waited Forever” kicks off a pieced-together so-called collaboration with four former key members, but they never actually played with Yes in the studio.

Yes, "Holy Lamb" from Big Generator (1987): YESterdays

Yes, “Holy Lamb” from Big Generator (1987): YESterdays

Yes, “I’m Running” from Big Generator (1987) YESterdays

“I’m Running,” the penultimate song on Yes’ 1987 album ‘Big Generator,’ steps out of the arena haze with an interesting but not totally successful gambit.

Yes, “Almost Like Love” from Big Generator (1987) YESterdays

When you add together all the disparate parts of “Almost Like Love,” you almost get a good Yes song … but not quite.

Yes, "Shoot High Aim Low" from Big Generator (1987): YESterdays

Yes, “Shoot High Aim Low” from Big Generator (1987): YESterdays

Yes, "Big Generator" from Big Generator (1987): YESterdays

Yes, “Big Generator” from Big Generator (1987): YESterdays

“Big Generator,” the title track from Yes’ 12th studio album, seems desperate in its need to sound modern.

Yes, "Rhythm of Love" from Big Generator (1987): YESterdays

Yes, “Rhythm of Love” from Big Generator (1987): YESterdays
