Music, like life, is well observed for moving in reoccurring formations, or cycles. In Los Angeles, each time a cycle comes, it tends to carry some of, but not all, the same structural properties it did on its previous occurrences. This can be seen in pop, experimental, in a view of the jazz world, as well as really in any genre.
When certain sounds return in some form, it's not necessarily in the full original structure. Rather, music returns through the prism of all that has progressed in between, becoming referential in nature. Reoccurring and brand new, as it all comes back around, all is new again in a fresh form.
As a musical artist, you too also have natural cycles of creativity, and you may find that you come back to ideas you had before but now with fresh perspective. When you return to a portion of your own creative cyclical structure, it may be in a somewhat new context or form.
Ideally, your creative drive and interests move in conjunction with the larger cycles of life, and of music, so that you find that you are part of a larger rhythm. So that you find fresh ideas return in new forms to you in successful synchronicity with the musical structure of the larger sound culture at a given time.
This represents being in the right musical places in the right creative time.
