Ryan Speedo Green will sing “La Boheme” in tonight’s performance.

The Metropolitan Opera announced that due to illness Matthew Rose would not be able to perform the role of Colline. As a result, Green will replace Rose.

Green is currently performing in the Met Opera’s production of “Aida” and will be featured on HD on Oct. 6. He will also give a recital at the Washington National Opera as the Marian Anderson Vocal award winner.

Rose returns to “La Boheme” on Oct. 6 and is also slated to perform in “La Fanciulla del West” as Ashby when it opens on Thursday, Oct. 4.

Green stars alongside Vittorio Grigolo, Nicole Car, and Angel Blue. James Gaffigan conducts the performance.
