What is the name of Elton John's Las Vegas residency that began in 2004?

The Red Piano was the name of Elton John's Las Vegas residency that began in 2004.

The residency opened at The Colosseum at Caesars Palace on 13 February 2004. Its staging used a large red piano and elaborate visual projections, creating a theatrical concert built around John’s catalogue of popular songs. Photographer and director David LaChapelle contributed to the show’s visual design.

The Red Piano ran for several years and became closely associated with John’s Las Vegas performances. It is distinct from The Million Dollar Piano, a later Caesars Palace residency that began in 2011 and used a custom instrument featuring LED screens. Because both shows were long-running Las Vegas productions, their titles are a common source of confusion.
