"If it's too loud, you're too old." Kidding, of course.
Audiology is going to be a growth industry sometime in the next 10-20 years as my generation pays its dues for loud rock concerts and walkmans.
Still, it's not a moral issue, but an issue of taste. Christians do poorly when they confuse the two.
Er! What's that you say sonny! :o)
Perhaps I’m a bit nostalgic but I remember the Christian concerts of the 70s such as Phil Keaggy. They were generally small, the artists would take time out to share their perspective and love of God, there might be ushers in the crowd to answer questions for nonbelievers who you were encouraged to bring along and the music generally reflected the person’s testimony. We recently attended an Avalon concert last spring which was reminiscent of the early concerts I’ve attended. While the music during their concert was loud it was not unreasonably so, they presented a solid testimony and it was a good experience.
Another concert we attended (the one with the ear plugs) was not that way at all. It was a “glitzy”, ecumenical show with little (almost no) mention of our Lord Jesus-just "God". You literally could not hear the lyrics of the songs and one of the artist boast of “getting loud”. I took my younger son with the hopes that he would hear solid, talented men talking about their love for our Lord Jesus. All we really got was noise.
I’m not labeling all Christian artists as bad nor am I going to judge them. But I don’t believe singing a chorus 25 times over and over again is edifying to your Christian walk. And if you can’t understand what is being said and there is no testimony, what’s the point? It really becomes an entertainment value-not a Christian experience. And that's what music in many of our churches has become-entertainment, not worship.
