This whole post just makes me feel awkward and uneasy.
To the 'mates: Much respect for defining your own distinct sound and sticking to it, every group should hopefully try to find a niche for itself and grow within it and try to expand beyond it whenever they can. Regardless of if you hate block chords, or you love them, if thats the way the group wants to go, no one can bash your reasons - but they can decide if they like it or not.
FYI: Juxtaposition has taken the last 3 years to redefine and filter its sound - after a CD which got 'ok' reviews (4.3 i think) and going to ICCA Finals in 2004, the group learned some very important things. From live performance, to image, to competition, to recorded CD. For the reason of having their own defined sound and sticking to it independent of the a cappella world around them.
As a whole, Juxta stays away from block chords. We like complex arrangements with interweaved parts and strategic highlighting of each vocal part in each song. We aim for truness to origonals, as well as, our own unique touches on songs. We always aim for words over syllables (a jin, jow, chang will not be found in many tracks). We pride ourselves on live performance, and preserving live performance aspects on our albums, while still hoping to explore, experiment, and exploit all of the recording technologies and techniques available to us.
So, some people will like that - some people will not - but we pride ourselves in our work, and hope that as many people as possible enjoy listening to us perform.
[Note: This is only my personal image of the group dynamic after my two years there...however, I hope it gives some perspective. Be yourself, enjoy your music, explore options but remain defined.]
