Stay tuned for some exciting MDD news as well about the upcoming album. The band is unsure yet of who the replacement will be, but in the meantime they will continue on as a 4 piece. Thanks to all our fans for your continued support."
The news came on the heels of the band renting a home to work on their third studio album and after Costa had posted that he had gotten married on Thursday.
With fans reeling Costa followed up the band's post with a statement of his own,
"ATTN FANS: It is true. I am leaving My Darkest Days. I was hoping to announce this in the upcoming few days as I have been celebrating some of my life milestones. However, the press release has been made, so I owe it to you all to tell you from the person himself. Please see below. The past 4 years with My Darkest Days have been an incredible journey and an amazing experience. I will be forever grateful for all that the band has contributed to my life and career.

I’m looking forward to the next chapter of my musical career and sharing it with all the amazing fans. I can’t wait to share a bunch of new music with you all in the near future. This is not the end… this is just the beginning Please ‘SHARE’ this post as I want people to hear the news from me, rather than broken telephone. All the best to MDD. Much love. – Sal"

Their second album, 2012's Sick and Twisted Affair, debuted at number 29 on the Billboard 200 and number 9 on the Billboard Rock Album charts.
