Singing the blues over a few grey hairs? Don't worry about it. Consider how Johann Sebastian Bach would feel this year getting ready to hit 300. Although birthday isn't until March 21, you can get a jump on the big guy's tricentennial this weekend. The Friday Morning Music Club starts things off at noon Friday with a 300th anniversary piano concert. Scheduled works are Bach's Goldberg Variations; Brahms' Fantasies, Opus 116; and Schubert's "Wanderer" Fantasie, Opus 15. The concert will be at New York Avenue Presbyterian Church, 1313 New York Avenue NW. If you're taking Metrorail, exit at the Metro Center station. 588-1895; free.

Or, you can celebrate on Sunday with organists, an ensemble of baroque instruments and a choir. At 3:30 p.m., local chapters of the American Guild of Organists will perform some of Bach's organ works, to be followed by a vespers service at 4 highlighted by Bach's motet "Singet dem Herrn" and other works. It's at the United Church at 20th and G streets NW. If you're taking Metrorail, exit from the Blue or Orange lines at the Farragut West station. 331-1495; free.
