Recognized as the best vocalist, (XIA) Junsu has returned to us with his 2nd full-length album, which contains his mature sensibility and various genres.

The biggest feature of this regular 2nd album is the attempt of various genres. Composer Jeon Hae-seong, who participated in the first album, Rain, MBLAQ producer C-Luv aka Tae-wan, Chairman (Seo Hyun-il), who produced the dramas 'That Winter, The Wind Blows' and 'Gu Family Book', and Dr. Kim (Kim Dae-hyun), who participated in Brown Eyed Girls' and Lyn's albums, joined in to present new styles such as dance ballads, neo-soul, and throw jams.

In the 2nd regular album, XIA (Junsu)'s vocals wore a variety of colors. From the emotional ballad '11:00 It's Right', which was completed with only natural vocals and acoustic rhythm, to an authentic ballad with dramatic grandeur, a medium-tempo dance song suitable for the season, authentic R&B and hip-hop rhythms with impressive brass performances. Up-tempo, here, the vocals of (XIA) Junsu, which he first tried as a vocalist, such as neo-soul and funky, are in full bloom with various flowers, giving listeners a rich sense of happiness with a rich scent.

The song that stands out the most is the title track 'INCREDIBLE'. Rendezvous with Sony Music composer 'AUTOMATIC', who made a big issue with XIA (Junsu)'s US single 'UNCOMMITTED' last year, this song is an exciting and powerful dance song that goes well with summer, and the beauty of a woman. It meets XIA (Junsu)'s delightful lyrics about the song and emits passionate energy.
