NMIXX has captivated fans' hearts with visuals bathed in the brilliant summer sunshine.

NMIXX is set to make a comeback by releasing their third single, 'A Midsummer NMIXX's Dream,' and the title track 'Party O'Clock,' on July 11. In anticipation, JYP Entertainment unveiled 14 teaser images hinting at the new album's concept on their official SNS channel at midnight on June 27.

The revealed photos capture NMIXX in a languid yet relaxed atmosphere amidst a summer day. The warm tones and soap bubbles scattered around create a mysterious ambiance, while members LILY, Haewon, Seolyun, BAE, Jiwu, and Kyujin perfectly flaunt their vibrant visuals in a variety of striped patterns, raising anticipation for the comeback.

The title track 'Party O'Clock' is a song penned and composed by JYP's chief producer, Park Jinyoung, and marks the first collaboration between NMIXX and Park Jinyoung. It has attracted the attention of K-pop listeners both domestically and internationally. The pre-released track 'Roller Coaster' has lyrics written by hit lyricist Seo Ji-eum and was composed by the famous production team NuVibe Music, which produced TWICE's 'The Feels' and ITZY's 'Cheshire.'

Since May, NMIXX has been conducting their first solo showcase tour, 'NICE TO MIXX YOU,' meeting with fans (known as NSWER). In the tour, unfolding across eight North American cities including Seattle, San Jose, Los Angeles, Dallas, Houston, Atlanta, Washington D.C., Brooklyn, and additional 13 overseas locations like Bangkok, Jakarta, Taipei, Singapore, and Manila, NMIXX is proving their status as 'K-pop's 4th generation top talent girl group,' showcasing balanced abilities in performance, vocals, and visuals.

Meanwhile, NMIXX will pre-release the track 'Roller Coaster' along with its music video at 6 p.m. on July 3rd, and officially release the title track 'Party O'Clock' and the third single album at 6 p.m. on July 11th.
