I want to check how is the sampling of an artist that I know well, and so I decided to perform ancestral sampling of the Jukebox 5b model of two artists whose catalog I know well: Joy Division and Lucybell. While the former is pretty well known and has just a few official albums, the latter is my former band which happen to be in the V3 list of artist, which is tied to the 5b and 5b_lyrics models.

For Joy Division, I requested 16 samples with sample_length_in_seconds=60, in five genres (Dark Wave, Gothic, Coldwave, Hip Hop, and Glitch Pop). It took:

    Nodes: 1
    Cores per node: 6
    CPU Utilized: 14:55:31
    Job Wall-clock time: 14:59:55
    Memory Utilized: 23.10 GB

For Lucybell, I requested 3 samples, 60 seconds. Note more than five times the number of samples didn’t take five times longer. Also, memory used for Lucybell was actually a third larger. Perhaps this is because I ran these two processes in two different clusters. I requested the same GPU though (Volta V100).

  Nodes: 1
  Cores per node: 10
  CPU Utilized: 08:05:34
  Job Wall-clock time: 08:05:12
  Memory Utilized: 31.02 GB

Joy Division samples

Some of the samples sound (e.g., item 0)like a rehearsal in a garage, or a live bootleg take. This is actually possible, since Joy Division has several bootleg albums. Other samples sound such another band (e.g., item 1, item 10, item 11, item 13), but from the same period and similar style and sound (i.e., post-punk, punk, or somewhere there)

From what I remembered, item 2 is the one that sounds closer to Joy Division. The shout at the beginning is very similar, I think, to one in a Joy Division song. Another examples sound very similar to you could expect from Joy Division (e.g., item 10)

Some examples seem to be strange parts of the model (e.g., item 12, item 8), where there is lots of silence.

My favorite ones are item 14 (rhythmically interesting and nice attitude) and item 3 (very nice mood but not Joy Division-ish, at all!)

It seems that the query is somehow close to the period and style attributed to Joy Division, but it is not actually retrieving and decoding something memorized The songs seem to be correctly tuned, there are no weird shifts in tuning and seem to be consistent over time and across songs

Lucybell samples

The three examples are in the form of a guitar-driven ballad, which is actually very close to most popular songs of Lucybell. It is interesting that all start in a similar way: a leading instruments, such as a solo guitar or leading piano. The second example (item 1) has a very nice phantom choir that accompanies the lead vocal.

None of the examples sound very Lucybell to me, but the there is something stylistically similar.
