Just a week shy of their very long-awaited comeback and four-member K-Pop girl group miss A have released the first teaser image for their upcoming album release and new song "Hush."

The miss A members appear silhouetted in an empty warehouse wearing sexy black outfits in the black and white teaser image announcing the release date for the group's second studio album.

The concept for the comeback appears to be dark and mysterious sexiness.

There has been a lot of buzz surrounding the upcoming album and single, both titled "Hush," as it has been a year since the Chinese-Korean girl group released their last EP, Independent Women Part III, under their label JYP Entertainment.

Additionally, there has been a lot of talk about the new single as it will mark the first time a lead track for the miss A has not been composed by their agency's CEO Jin Young Park.

"Hush" is the work of composer E-Tribe and is one of thirteen tracks on the upcoming full-length album.

Other songs on Hush were written and composed by more familiar names like Lee Woo Min, Park Woo Sang, and No Day.

However, there has been a lot of shock and confusion as the one name everyone expected to see plastered all over the album's credits, that of Jin Young Park himself, is curiously missing.

According to a statement from a JYP Entertainment rep, "Among miss A's albums, this is the first time their title song is not J.Y. Park's. As the songs we received were all good, this time we created a dimension in which we worked with new composers. There is really no other reason."

Another insider revealed the reasons for going with songs composed from outside the company was simple, "It's not that we have been purposely using only J.Y. Park's songs, we've always received songs from various composers and went with the song that had the best feedback. This time around, we decided on E-Tribe's song."

The company also said that the girls are hard at work in rehearsals perfecting their routine and practicing for this highly anticipated comeback to the K-Pop scene.

Stay tuned as more teasers and info are released about miss A and their new album Hush, which is scheduled to drop on November 6.
