I have just acquired a marvelous box set: The Complete Blue Note Elvin Jones Sessions. It contains eight CDs with the contents of maybe nine original LPs recorded between 1968 an 1973. I've posted a couple of cuts from this collection but I have only started listening to it.
I also purchased a recording by Empirical: Opt' n' In'. This is a tribute to Eric Dolphy. I have posted one cut on the recording: 'Hat & Beyond', an obvious nod to Dolphy's 'Hat & Beard', from his seminal recording Out to Lunch. If I have time, I'll write more on these recordings.
