Bostonist loves ourselves some opera, but sometimes theaters and and concert halls and opera houses all seem too obvious. In a city where you can get it with your oysters, or your popcorn, you should be able to get it with your beer: this is why Opera Boston Underground is inevitable.

Combining a cozy subterranean venue (the Lizard Lounge, under the Cambridge Common restaurant at 1667 Mass. Ave.), a negligible cover ($8), and an impeccably-curated beer menu (Saranac! Otter Creek! CBC!), Wednesday night's "opera cabaret" promises "Spanish zarzuela arias, Latin American songs, and excerpts from Ainadamar" sung by mezzo-soprano Glorivy Arroyo and tenor Christian Figueroa and other young, talented things, for not even a quarter of the cost of the most obscure seats at Ainadamar. There are no advance ticket sales, so we recommend arriving well before doors open at 7 pm: Bostonist's attempt to attend their first, Weill-oriented show was thwarted by a line around the block, and we were left shivering on Mass. Ave. with a patient friend and some sorely disappointed Cambridge ladies and their shawls.
