Tues. Oct. 16

 We suppose we wouldn't argue if someone said "Boston Symphony Orchestra" and you thought of Beethoven, whose name is above the stage, and all the other dead European guys whose ghosts are floating about.  Symphony Hall. Fact is, as wonderful as Hadyn, Bach and Beethoven were, the BSO is not rooted to any particular century. Consider what's been up over the past weekend (and closes Tuesday Oct. 16).  It's a work called "The Garden of Cosmic Speculation" - my word, it sounds like an early Pink Floyd album! - by local composer Michael Gandolfi, who has international recognition and currently teaches at the New England Conservatory. Gandolfi's The inspiration for this particular piece being is architect Charles Jencks’s book of the same name, an extensive photographic documentation of a Scottish garden designed by, well, Jencks. The garden is a series of plots or zones, each of which was inspired by a scientific concept, from the smallest of concepts (quarks and DNA) to the largest (to structure of the universe). Gandolfi’s music is the second level of translation: he responds both to Jencks’s designs and to the concepts that inspired them. Sounds obsessive, ambitious and wholly intriguing. Who says science and art live in different worlds? Check out Gandolfi's website www.michaelgandolfi.com for more info. The final show is Tuesday Oct.16 at 8 p.m. Tickets: $103-$29.
