Both boy groups have released some tantalizing teasers that highlight the transition from summer to the more mellow Autumn.

BtoB and GOT7 are both planning on returning with new albums next month, and teasers are in full swing. Born to Beat plans to releases Brother Act October 16, while GOT will release 7 for 7 on October 10.
