Francis A. & Edward K. is a duet album released in 1968 by Reprise Records, bringing together Frank Sinatra (Francis Albert Sinatra) and Duke Ellington (Edward Kennedy Ellington), combining Sinatra's voice with Ellington's orchestra and arrangements.
The recording sessions took place in January 1968 in Los Angeles, with arrangements by Billy May and musical direction by Duke Ellington, although creative tensions between Sinatra and Ellington led to some tracks being re-recorded without the full participation of Ellington's orchestra.
The album reached number 78 on the Billboard 200 chart and, while not a massive commercial success, it is valued by critics as a unique collaboration between two giants of 20th-century music, highlighting the fusion of swing and orchestral jazz.
