A fine program including infrequently heard works by C.P.E. Bach, Handel, and Haydn made the evening worthwhile, especially for the singing of Ms. Baird. The harpsichord and fortepiano solos, on the other hand, were barely up to undergraduate recital standards. Ms. de Silva is an uninspiring performer, wooden and seemingly interested only in hitting the right notes, investing little personality or sense of artistry into her mechanical renditions of the various harpsichord and fortepiano solos on the program, a wan imitation of the master harpsichordist Trevor Pinnock who performed at LC a year ago. Well known for her command of the baroque repertoire, Ms. Baird was engaging and lively whenever she sang, even accompanied by a less than sympathetic Ms. de Silva. Her singing made the evening worthwhile, and with another accompanist it could have been excellent.
