I expected musical love in the Quad City Symphony Orchestra's Valentine's concert on February 11, but I was surprised where I found it.

Guest conductor Alondra de la Parra programmed familiar "romantic" music in Nicolai Rimsky-Korsakoff's symphonic narrative of Scheherazade (a princess whose beguiling stories prevented her execution and ultimately led to marriage) and Maurice Ravel's Bolero, made popular by the sexy comedy 10. Yet Spanish composer Joaquin Rodrigo's guitar concerto - inspired by his wife - and a rousing and unexpected Latin American encore captured my musical heart.

Rarely and unpredictably, a performance will transcend music and become a living thing, a forceful creature that grabs the audience and won't let go until the piece ends; it then lingers for hours in the mind. These experiences transport me beyond what Gustav Mahler called "the sounds of a garrulous world" and overshadow the conductor and musicians - not because they're unimportant, but because the life-giving in their performance is so profound. On Saturday at the Adler Theatre, the beast arrived after intermission when the Quad City Symphony Orchestra and Music Director and Conductor Mark Russell Smith breathed life into Johannes Brahms' Symphony No. 1.

The titles of the first two Masterworks concerts in the Quad City Symphony Orchestra's season indicate a distinct shift - from the pure music of Beethoven 5 (named for the showcase piece) to the literary-themed Poems on Fate.

Concert planners were obviously aiming to demonstrate the symbiotic relationship between language and music in the November concerts. But somewhere between the idea for Poems on Fate and the selection of its music, the conceptual glue lost its cohesion. The audience's perfunctory response at the Adler Theatre on November 5 was in stark relief to the profuse applause and standing ovation that greeted Beethoven 5's first performance, and it was clear that something had gone wrong.

All four pieces in the Poems on Fate program clearly fit the theme. Johannes Brahms' Song of Destiny used text from a poem, Giuseppe Verdi's opera La Forza del Destino a libretto, and Richard Strauss' Death & Transfiguration and Franz Liszt's Les Preludes inspired poems that were included as prefaces in their published scores.

The challenge for program planners was to maintain the integrity of the musical experience while coherently demonstrating its connection to literature. (It would have helped if the prefaces had been included in the printed program, to provide a fuller literary context for the audience but also to demonstrate the florid style characteristic of the period when the music was composed.) And while the literary connections worked, the music, as a program, didn't.

Passion proved to be the Quad City Symphony Orchestra's strength in its season-opening program at the Adler Theater on October 1, but the performance was vulnerable to imprecision.

While the program was titled Beethoven 5, the highlight of the concert was a brilliant performance of Sergei Rachmaninoff's demanding Third Piano Concerto by guest pianist Haochen Zhang with bold yet sensitive accompaniment by the symphony under the direction of Music Director and Conductor Mark Russell Smith.
