You are very close but you are restricting your "rules" a bit too much. Try "relaxing" what you tell Web::Scraper to expect. To prevent hitting the site too much, I saved the output into a file named lee-morgan.html. I've taken care of scraping out the release date and the bio paragraphs, let's see if you can obtain the rest. :)

use strict; 
use warnings;   
use Data::Dumper;
use Web::Scraper;
            
open FH, 'lee-morgan.html' or die $!;
my $data = do{ local $/; <FH> };
close FH;       
            
my $artists = scraper {
    process '.release-height > p', 'bio[]' => 'TEXT';
    process '.recording-dates > h3', date => 'TEXT';
};

my $res = $artists->scrape( $data );
 
print Dumper $res;
