Digitally remastered edition contains both the stereo and mono editions of this classic album. Ella Fitzgerald At The Opera House was originally issued both in stereo and mono versions. While the stereo LP presented the actual Opera House performance, the mono recordings contained a similar performance at the Shrine Auditorium in Los Angeles. Both concerts are presented on this edition, which also includes a rare reading of 'How High The Moon' appearing here on CD for the first time ever. Poll Winners. 2010.
