A very straightforward release from the Corrs, who spend the majority of this outing in full-blown pop mode, with the Celtic elements mostly being relegated to the backgrounds of several songs. The one exception is the closing instrumental, "Rebel Heart," which stirs itself up full-bloodily to provide the album with an anthem. In Blue is a bright, peppy set that bears more than a few comparisons to the work of bands such as the Bangles and Fanny, though the Corrs have an additional advantage in that Caroline Corr is an impressively muscular drummer.
