After revealing simple yet alluring teaser photos,�SPICA has officially announced their comeback!

B2M Entertainment recently updated with the jacket photo from the group's second mini album, 'Lonely', which will be released on November 21st as reported previously.

The jacket photo showcases a feminine, yet strong image of the girls that is very different from the first batch of teaser photos revealed earlier.

The group's new work is said to have been produced by hit team Sweetune, and the members have also included their own works as well in the album.

Not much else is known about their upcoming title track "Lonely", except that it is a "retro-feeling sound with a sophisticated beat".
