The votes are in. The people of Scotland have chosen to remain in the United Kingdom. To mark the historic occasion, a wee reminder of what the Scots have contributed to classical music is in order.

Almost any pianist, from a budding beginner to a pro like Simone Dinnerstein, will tell you that one of the basic techniques of keyboard playing is also the toughest to master: making your hands to do separate things simultaneously.

Arvo Pärt is one of the few living composers to find popularity beyond the borders of classical music. R.E.M.'s Michael Stipe and Bjork are big fans.

The Bee Gees did it. So do Smokey Robinson, Prince and Justin Vernon of Bon Iver. They all sing in the high register usually associated with female singers.

In 1986, four women gathered in a casual setting to sing through a bit of medieval chant. Little did they know they were launching Anonymous 4, an a cappella ensemble that has spanned nearly 30 years, 20 albums, countless concerts and more than a millenium of music.

Today the group announced that the 2015-16 season will be its last together. But this isn't the first time Anonymous 4 has thought about calling it quits. The group bid a similar farewell in 2004.

In much of the country it still feels like summer is a long way off, but it's not too early to plan on hitting the road and hearing great music. From bucolic college campuses in New England to musical rafting trips down the Colorado, these are 10 of the most intriguing classical festivals. And below them is a listing, by region, of many of the best fests. Been to one we missed? Pass along your own advice in the comments section or via Facebook or Twitter.

Soviet composer Vadim Salmanov is little more than a footnote outside Russia, but his four energetic, skillfully orchestrated symphonies are making a small comeback. Russia's venerable Melodiya label has reissued them in a handsomely packaged double-disc set of live recordings made between 1957 and 1977.

Conducted with burning intensity by Yevgeny Mravinsky, Salmanov's rarely heard music soars off these albums with a sound that is thoroughly Russian yet charged with a certain Soviet-era anxiety.

Johann Sebastian Bach wrote his St. Matthew Passion for a single purpose — to present the Passion story in music at Good Friday vesper services.

Bach's Passion continues to move audiences nearly three centuries after it was first heard in St. Thomas's Church in Leipzig, Germany. Standing as one of the pillars of Western sacred music, it is at once monumental and intimate, deeply sorrowful and powerful.

John Luther Adams, whose music is inspired by — and sometimes performed in — natural landscapes, has won the Pulitzer Prize for music for his symphonic work Become Ocean.
