Still listening to the David W. Niven Collection of Early Jazz Legends, 1921-1991. He gives short intros and then every track is a like a mixtape – 600 hours or more! Currently listening to Oscar Peterson. At the time I used an elaborate torrent setup documented on my website to download them all. But there’s also a list of URLs to Ogg files, if you prefer that. Getting them all takes time but three years later it’s still paying off.
