if you're a fan of bluegrass music then you'll appreciate this dvd. the sound and video aren't the best there is, but the music and interviews are mighty fine, especially if you're a fan of del mcoury, he's featured in 3 songs on the disc. there's also a bit of a young michael cleveland jamming with doc watson that's very interesting, as well as the bluegrass youth allstars. i've had this on my wishlist for a long time, but i wish i would've bought it a lot sooner, just wasted time by waiting for the right price ($3.27). it's well worth the price that's up right now. buy it!
