We Boom is the third extended play of South Korean–Chinese boy band NCT Dream, the third and teen-aged sub-unit of the South Korean boy band NCT. Released by SM Entertainment and Dreamus digitally on July 26, 2019, and later physically three days later, the EP consists of six tracks, and is the first release of the unit to not contain any Mandarin version for the lead single.[1] SM founder Lee Soo-man continued as the release's executive producer, while several songwriters and producers, such as Ryan S. Jhun, Yoo Young-jin, Sonny J Mason, Deez, Moonshine, Cazzi Opeia, Benjamin Ingrosso, Livvi Franc, Louis Schoorl, Bobii Lewis, Jamil `Digi` Christmas, MZMC, and others, contributed both lyrics and production to the extended play. It was the unit's first major release as a sextet, following the graduation of member Mark in December 2018.
Commercially, the extended play experienced success in South Korea; it became the unit's third chart-topper on the Gaon Album Chart, their first release to receive a Platinum certificate by KMCA, and subsequently the best-selling release by an NCT unit in 2019. In the United States, the EP earned the unit their best sales week to date while becoming the group their second and third top-ten entry on the Billboard World Albums and BillboardHeatseekers Albums, respectively. In conjunction to the EP's promotion, "Boom" was released as the lead single, to where it peaked at number ninety on the Gaon Digital Chart, while barely missing out the top ten on the Billboard World Digital Songs chart. The song, however, was the unit's first entry on the New Zealand Hot Singles chart, debuting at number forty, and has since become one of the unit's signature songs. The unit has since performed several songs from the extended play on The Dream Show and their Beyond LIVE concert in May 2020.
