IMO, the 70's was the apex of the electronic age of music. Prior to the 50's, the only thing they had were strings, percussion, and horns. Then with the 50's came the electric revolution, which was mastered in the 60's, and peaked by the 70's. My favorite part about the 70's is how the music scene was filled with so much variety and it was more about the music than the genre or type. You had the singer/songwriters that got play, rock, funk, disco, R&B, and even country music crossover would get air time. Unlike a lot of "musicians" today, those artists all played their own instruments, and sang without the help from technology. The consolidation of record companies and radio stations that took place in the 80's was pure fucking cancer, and music has never recovered.
