Is “Heart of the Sunrise” about the power of the sun – or being lost in a city? Whatever the concept, this represents Yes at the peak of their powers.

Yes’ “Mood for a Day” probably isn’t the first Steve Howe solo guitar composition that comes to mind – but maybe it should be.

“I got back to England, after a very successful tour – and my phone rings at 11:30 at night,” Keith Emerson remembered. “It was their then-manager Brian Lane.”

“The Fish (Schindleria Praematurus),” from Yes’ 1971 album Fragile, is a fitting contribution from the late, great Chris Squire.

“Long Distance Runaround” is stuffed with progressive elements from Jon Anderson, producer Eddy Offord and Yes, only adding to its stature in the canon.

Bill Bruford frequently calls this Yes song, originally titled “Suddenly It’s Wednesday,” a starting point of his journey as a composer.

An amazing piece of music, “South Side of the Sky” is a platform for the best of Yes’ compositional, playing and arranging talents.

Preston Frazier’s Non-Jazz Best of 2015 list also includes Shemekia Copeland, Grupo Fantasma, Luke Reynolds, Public Service Broadcasting, the Westies and others.

Clocking in just over a minute and a half, Yes’ “We Have Heaven’ is essentially a Jon Anderson chant revolving around two themes.

This Best of 2015 list focuses on those revelatory moments, those times when a shard of pristine insight cuts through the clutter of expectation and then memory.
