What is it? Three prodigious sisters, the oldest aged 21, play traditional and modern bluegrass music with three-part harmonies. Last month, the Lovell Sisters played for thousands of people at MerleFest (the country’s premiere bluegrass festival) to roaring applause.

Why see it? The Lovell Sisters are going to be huge. They’ve been building their name since their first appearance on A Prairie Home Companion in 2005. At ages 21, 18, and 16 today, they’re already among the most talented acts on the bluegrass circuit. On top of fiddle, mandolin, and dobro, the voices of the three girls blending together is almost celestial.

Who should go? Much like Nickel Creek or Jerry Douglas, the sisters are easy on the ears while at the same time captivating and compelling. Any bluegrass fan will be duly impressed.
