In 1973, Pink Floyd released "The Dark Side of the Moon," which quickly went to be the greatest selling album of its time. The critically-acclaimed album was a composition that as a whole dealt with life, death, money, mental illness and the passage of time. Some even call it the greatest album ever written. This album was extremely experimental for its time, and today, causes many people to say "it's a shame people don't make music like that anymore."

The thing is, people still do.

Of course, no one has made an album like "DSOTM" or "The Wall" in a very long time, but there is still a huge amount of experimentation in music today that people don't seem to notice. The newest breakout group on the alternative scene, Twenty One Pilots is an excellent example of this. In their music, they experiment with reggae, pop, rap and a variety of other genres -- all within the same songs. They are pushing boundaries and are hard to define by a certain genre.

Another excellent example is Julian Casablancas + The Voidz. While their music is a little noisier (their genre is actually called noise rock) and abrasive to some, they are one of the most experimental groups today, layering guitars and synthesizers over politically-charged lyrics. Their song "Human Sadness" is, in my opinion, one of the most beautiful songs of the last 10 years. Along with these groups, you have groups like Tame Impala, The 1975, Cage the Elephant and Vampire Weekend, who are all putting out music that uses a huge variety of sounds and influences.

However, while many groups like this exist, they're not exactly mainstream. Even though The 1975 has a platinum album and two number one albums, they still receive almost no radio play and no mainstream journalism coverage.

For the people to find the music that they wish still existed, they have to look deeper than the mainstream. Go to a record store, scrounge the internet for new music, go to music festivals. The music is there, people just need to find it.
