Joshua Kosman hails Mason Bates' Alternative Energy as the most exciting work played by orchestras visiting San Francisco:
...Mason Bates' broad and inventive "Alternative Energy," for Chicago, was by far the most exciting new work of the series. I wasn't as taken with the pieces written for Los Angeles by Enrico Chapela and Esteban Benzecry, but they did give evidence of Dudamel's coherent tastes, just as the Boston performances of music by Elliott Carter and John Harbison attested to Levine's commitment to the patrician modernists. At the other end of the spectrum was Philadelphia, whose sole contemporary offering - a brief, bland curtain-raiser - was so feeble and begrudging that it seemed almost an insult.
