If you follow Sera on Twitter and YouTube you probably already know that the singer has been updating fans on the making of her new album 'Serenade.' In a three-part homemade video series she uploaded onto her personal YouTube account, Sera shared the behind story of putting her album together, all the way from A to Z. Interestingly enough, Sera was her own boss for the production of 'Serenade,' recording and editing her own songs, designing the album cover, and even applying for the rights to her musical work.�

Her family was a big part in this important process, with Sera's own brother lending a bit of advice on her jacket photos and her mother giving the album a listen, choking back tears from pride in her daughter.�

What's even more awesome is that Sera delivered her freshly-made CDs right to her fans' doorsteps! Though she couldn't deliver her CDs to everyone, fans still appreciated the singer's efforts to bond with them on a more personal level, taking the time to visit their homes.�
