"What artists or albums might you recommend?"
Tony Williams Quintet - Civilization, also Angel Street.
Michael Brecker - Tales from the Hudson, also Two Steps from the Edge
Mike Manieri's Steps Ahead - the self-titled first US release but also Smokin' At The Pit (originally, a Japan release only)
All these were recorded much later than "Something' Else" but I believe they are considered "hard bop".
Check out The All Music Guide for a given album and click on the "Similar Albums" tab for suggestions (although AMG casts a pretty broad net in terms of what they consider "similar").
