S.F. Symphony review: Foggy 'Drift' Just six months after its West Coast premiere, Samuel Carl Adams' "Drift and Providence" returned to San Francisco on Wednesday night, creeping back in on its foggy feet and filling Davies Symphony Hall with vague and intoxicating musical textures. Adams' evocative orchestral soundscape led off a strong concert by Michael Tilson Thomas and the San Francisco Symphony, the first of two weeks dedicated to a local preview of the orchestra's forthcoming East Coast tour. "Drift and Providence" sounded much as it had in September, with its themes slowly coalescing out of the primordial soup (an idea that Adams, like Brahms in his First Symphony, derives ultimately from the opening of Beethoven's Ninth) and its dense orchestral blur of brass and percussion. The rhythmic propulsion of the opening movement found its counterpart in the finale, grandly but graciously shaped as it drove toward the explosive conclusion.
