The AllMusic review by Al Campbell noted that "Nice Guys was the first Art Ensemble of Chicago album released after a five-year recording hiatus and the group's first for the ECM label. During those five years, the Art Ensemble toured Europe and continued to expand its compositional, improvisational, and theatrical jazz fundamentals, captured abundantly on Nice Guys... the album reveals how the AEC managed to turn individual compositions into a fully realized, surprisingly accessible, avant-garde group collective."[5]
DownBeat critic Art Lange writes that Nice Guys, while not the Art Ensemble's best album, "is possibly their most representative, a variegated showcase illustrating much of what they do best."[9]
The Penguin Guide to Jazz awarded the album 3 stars out of 4, stating that "much of the music seems almost formulaic, the improvisation limited".[6]
