^You should. I've listened to the whole first LP now, and it is GOLD! As a little side note though, I would temper that by saying that I know sweet fuck all about audio, so take my enthusiasm as wholly uninformed.
Oh also, got this for Christmas:
Amazing! It's Schlippenbach and a handful of other modern avant jazz greats doing a 3+ hour concert where they beast through the
entire Monk songbook like total madmen, just like BAM BAM BAM through each tune in these really unusual arrangements. It's fantastic, but pretty deranged after a while.
Edit: Oh, and can I point out that, on the evidence of the above gift, my mum is likely much cooler that yours.
