[3][4] On August 7, SM announced that Riize would be making their debut with the release of a single album, Get a Guitar.

The track was first teased on August 21, with a small snippet being included at the end of the music video for the group's previous single "Memories".

[15] The track interpolates the bassline from the 1980 song "Another One Bites the Dust" as written by John Deacon and performed by Queen.

Writing for NME, critic Carmen Chin noted that the song "feels like a breath of fresh air" and is "one of the year's standout debut tracks in the K-pop scene.

"[10] Robin Murray, writing for Clash, characterized the song as "a crisp slice of pop bedlam" and "incredibly infectious".

[24] The "Get a Guitar" music video was released simultaneously with the song on September 4, premiering on SM's YouTube channel at 12:00 AM KST.

[31] Styled in mock-claymation, the music video consists of the lead character travelling through different scenes while riding a guitar-shaped skateboard.
