Mayall returned to the studio in 1973 for this double album. The ten years Mayall
had in mind, of course, were the previous ten, which had seen him start as a local musician in Manchester, England, and emerge a decade, almost two dozen albums, and nearly as many lineups later with an evolved jazz-blues style and an international following. The album allows the ensemble considerable room to solo on Mayall's typically simple, blues-based song structures, and the approach is perhaps excessively casual. The second LP is a live date recorded at the Academy of Music in New York, and here things stretch out even more: "Harmonica Free Form" clocks in at 12 minutes and "Dark of the Night" runs 17:41.
