I rarely cross the streams, so to speak, between my blogging and musical lives. But I’m making an exception for this concert: Boston Lyric Opera and Boston Landmarks Orchestra are teaming up to present a free concert of some of opera’s greatest hits tonight (Wednesday, August 8) at 7 pm at the Hatch Shell on the Charles River Esplanade. I’m proud to be part of the six-member cast of singers. The music is beautiful; the setting is amazing; the weather is supposed to be perfect. So grab your picnic basket and lawn chairs, and come join us!
