The decision by a band to go without a vocalist will lead to either disaster or a determination to avoid redundancy. It’s the measure of separating wheat from chaff with instrumental bands. Add to that the fact that most bands live and die by the growth and maturity of their music. While niche music is a bit safer from this sort of unspoken principle, stagnation is still just one recycled riff away. With an instrumental band, that challenge becomes even more dubious. The onus for success in these situations lies solely in their music’s ability to provide an engaging, moving narrative without the safety net of a vocalist’s easily delivered persona.
