Halcyon Days is the eighth studio album by American singer and pianist Bruce Hornsby. The album, recorded with his touring band the Noisemakers, was released in 2004. It was Hornsby's first release with Columbia Records. One song, "What The Hell Happened", has been described as a rare example of the use of bitonality in a pop piece.
The album marked a return to a more acoustic, piano-driven sound that reviewers described as "pure Hornsby". Guests included Sting, Elton John and Eric Clapton. The tracks "Gonna Be Some Changes Made," "Candy Mountain Run," "Dreamland," and "Circus On The Moon" became concert staples, each showcasing the diversity of Hornsby's improvisations and the Noisemakers' live sound. Notably, Halcyon Days also includes a suite of solo piano songs—"What The Hell Happened," "Hooray For Tom," and "Heir Gordon"—which all have a "Randy Newman pastiche." Although the album was markedly less-risk-taking than Big Swing Face, it would be well-received as a "winning balance of [Hornsby's] tuneful and adventurous sides."
"Gonna Be Some Changes Made" was used in several Lowe's commercials from 2006.
