ZAPPA BOOTLEGS ON SPOTIFY ?

I was checking out Spotify earlier today, and I noticed two Zappa bootlegs :

• frank zappa: vpro radio piknik, uddel, june 18, 1970 (remastered)
      (2015, spotify, --, lilith records)

The famous 1970 Uddel concert. It got broadcast on TV and on the radio at the time, but, unfortunately, only audio recordings of the broadcast survived...

• frank zappa: the muffin man goes to college (live)
      (2015, spotify, --, sonic boom)

Another re-issue of the well-known April 26 1975 Providence concert. Featuring Captain Beefheart.
