Music critic: How well an underground rock group' s recordings sell is no mark of that group' s success as an underground group  After all, if a recording sells well, it may be because some of the music on the recording is too trendy to be authentically underground; accordingly, many underground musicians consider it desirable for a recording not to sell well
But weak sales may simply be the result of the group' s incompetence
Whether an underground group's recordings meet criteria that many underground musicians consider desirable is not a mark of that group's success.
