In the 1960s, when I started listening to jazz, I passed over a lot of hard bop records because of their formulaic quality. Later on - late 70s to the present - I was able to get past the formulas and hear the musicians and the music. I missed out on some great music back then, but I'm lucky enough to be able to hear it now - and can hear it differently than I could have back then.
I don't find Leeway a boring date at all. Three of the tunes are taken at similar medium tempos, there's no ballad, and only one uptempo tune. Perhaps that's what Big Al is tuning into. Some fine solos throughout, and good tunes - a good record, to my ears.
