Though little is known about London trio London Grammar, their first single "Hey Now" serves as a great introduction. The ethereal, beautifully haunting record features the amazing voice of Hannah Reid. Imagine Florence Welch meeting Jessie Ware and there's Hannah, setting the bar for the trio's future releases. Daniel and Dot are listed as the two other members of London Grammar, and hopefully the trio will yield more information on their history. Until then, check out "Hey Now" below.
