1D fans everywhere have been eager for updates on the second solo album due from the internet-breaking boy band's alumni: Niall Horan, whose debut single "This Town" hit no. 25 on the Hot 100 this fall, appears to be next in line after Zayn Malik -- though no release date for his project has been confirmed.
One detail Horan has shared, though, is the producers he's been working with. In a recent letter to his fans on Dec. 5, Horan shared that he's been in the studio with Jacquire King (Kings of Leon, James Bay) and Don Was, the Blue Note president who, as Horan put it, "is a complete legend and has produced anyone from The Rolling Stones to John Mayer to Bob Dylan." He continued, "For me to work with this calibre of producer is pretty amazing really and I'm humbled that they wanna work with me."
