If you’re an audiophile, this is worth checking out.

The Boston Symphony Orchestra (BSO), comprised of some of the most talented musicians on earth has for 75 years been a part of Tanglewood, a summer long music festival in Lenox, Massachusetts, which features genre-spanning artists throughout. To celebrate its 75th anniversary, the BSO is releasing historic recordings from performances, which date back to 1937, the first year of the festival and beyond.

You can stream today’s offering, an original composition for the festival titled “Tanglewood Concerto” and written by Ed Sauter here, but snippets of what’s still to come can be heard over at the Huffington Post.

Listen to the crackle that permeates throughout Mozart’s Symphony No. 25 in G minor as recorded in August of 1937. Compare that to the 1955 recording of Bach’s Suite No. 2 in B minor. What a difference eighteen years makes. Not only is it a brief history lesson in music, but of the quality of reproduction. As music evolved, so too did the way we hear it and that’s often equally as interesting to examine.

For a full list of concerts at Tanglewood this summer, check out the lineup. I’ve maintained for a while that music lovers should experience a classical concert as it’s a truly unique experience. Just remember not to clap until the whole piece is over. Do not, I repeat, do not clap in between movements. Every fiber of your being will want to clap to break what is one of the more uncomfortable silences possible in a group consisting of thousands, but don’t. You’ll be the only one clapping. There are some weird etiquette rules that go along with this real high brow stuff.

Oh, and Evanescence is playing there too. So, I mean, if that’s your thing…
