After revealing two teaser photos of completely different concepts, the girls of 4minute have just unveiled their 2nd teaser video for 'Volume Up'!

'Volume Up' will contain a total of eight tracks, which is a high number for a mini album. The girls will be trying out new genres and musical styles they have not yet tried before through songs composed by hit maker Shinsadong Tiger, as well as other top composers.

Although their comeback isn't until next week, the group has launched a teaser site on their official homepage (www.4min.co.kr) to hype up excitement for 'Volume Up'.

Stay tuned to allkpop for the official album release on April 9th.
