Lights and Sounds is the fifth studio album by American rock band Yellowcard, released on January 24, 2006, in the United States through Capitol Records. Lights and Sounds is Yellowcard's first concept album, which was inspired to reflect what the band was feeling at the time of production and how they have matured in the process.

Upon the album's release, it charted at number five on Billboard's 200 and Top Internet Albums' charts, making it the band highest charting album to date.

In December 2004, vocalist Ryan Key and bassist Peter Mosely moved to New York City to write songs for their upcoming album, while the rest of the band remained in Los Angeles. As Key and Mosely stayed in New York, they admitted that there was a delay when it came to start writing songs for the album. Key, however, did explain that they were writing "weird, obscure, not-too-mellow" tracks and working on notebooks that he compiled while the band was touring. He also noted that he was able to write for a couple of hours and would receive over "15-20 ideas" that he could take out for the band, so once they
