Nell will greet fans with a new single for this winter season.

On December 11th, Woollim Entertainment uploaded a teaser photo on official Twitter with a message,"#Nell is releasing a new single 'Green Nocturne' to embrace this winter. Look forward to Dec. 15th, 2014!".

The company said,"Nell won't release any new album for this year. The new song just naturally came out as they were in the midst of preparing for their year-end concert". In particular, 'Green Nocturne' is said to be an acoustic song which fits perfectly with this season.

Meanwhile, Nell will hold 'Christmas in Nell’s Room' concert on December 24th.
