Red Velvet made a complete comeback after 2 years and 2 months since their June 2024 release 'Cosmic' with their summer mini-album 'Velvet Summer.' SM Entertainment released the album on the 3rd at 6 PM, featuring the title track 'Surfin' Boy' and four other songs totaling five tracks. The title song is a dance track characterized by a refreshing sound and dreamy vocal harmony, with lyrics written solely by member Joy that evoke memories of the hottest summer and create new brilliant moments. Red Velvet sold out their fan concert held from July 31 to August 2 at Hwajung Gymnasium, demonstrating fans' anticipation, and celebrated their 12th debut anniversary on the 1st by cutting a celebration cake together. Members shared in interviews that they deeply missed their time together as five members, expressing hopes that their growth from solo activities and artistic maturity are well-reflected in the album.
