Triskaidekaphobes (those who fear the number 13) may find some significance in the fact that the brass sounds a little less crisp, the vocals less penetrating and the usually rich Chicago sound is sometimes murky on the group's 13th album. Maybe the problem is that the Chicagoans have set such high standards for themselves in their previous 12. In any case, objectionable symptoms of discomania afflict the cut Street Player—which also squanders a guest appearance by jazz trumpeter Maynard Ferguson. Nonetheless, at least three tracks—Window Dreamin', Reruns and Run Away—are splendid enough examples of Chicago's ensemble rock to hold the faithful until No. 14 comes along.
