Change is constant. It is a continuous process especially in the music industry where fashion trends and tastes continually change. Hence, it is necessary for any band to stay successful to release music that appeals to popular audiences. However, music is about self expression - one can not be satisfied unless the music one creates is expressive. This doesnt mean that Nickelback are creative or not, they are new to popular music charts and like other bands that burst on to the charts, they have discovered a formula that works, or worked. They are not experienced enough to realise that a such formulae are not the key to a long musical career.
Metallica is the perfect example of minimal use of such a formula which has lead to a long standing musical career. Metallica were revolutionaries in the 80's releasing music that was not only popular at the time, but also integrating self expression in order to create a new style. Metallica are unique. However, unlike most bands today, they realised quickly that they can not release simply another version of their hits. From "Kill'em All" to "St. Anger" - Metallica have continuously changed. I agree with this article because I purchased "St. Anger" and refused to listen to it - until I realised that Hetfield and Ulrich have always aimed to create new and fresh sounds. "St. Anger" is not about chart topping and selling millions of records, but it is about self-expression. The band has rediscovered their roots by writing with their hearts - the result is an album filled with expresive lyrics and emotionally charged, however simple musical arrangements. Bands and artists must realise that music is not about selling records. Music is about self expression - the popularity of an artist should not depend on how many records they sell, but rather their dedicated fan base and performance skill.
This will soon turn into a thesis unless I cut it off. If anyone has a response, please take the time to write one because I feel strongly about this issue - thank you.
