most days i use Bart to get to work, and i’ve found that on weekdays musicians will perform in certain stations. happily, the same stations i frequent :-)
mornings at Embarcadero and Montgomery St stations can be anything from classical to folk music, or even a cappella. 16th St sees more in the evenings – typically folk/rock guitarists, a concert violinist (who also does mornings – sigh!), and on the rare occasion this cellist..
sometimes i don’t even realized i’ve stopped to listen until the song has ended. <3
