I know you asked for a XML::Twig solution, but it would not be me if I did not suggest a XML::Rules one instead. It would be something like this:

use strict;
use XML::Rules;
my $parser = XML::Rules->new(
  stripspaces => 7,
  rules => {
   _default => 'content',
   Copyright => 'no content',
   # ...
  Record => sub {
    return unless $_[1]->{Title} eq 'Something';
    print "The stuff in the %{$_[1]} hash containing the attributes an
+d subtag data.\n";
    return;
  }
  }
)

$parser->parse($file);
[download]

The rules will allow you to ignore the subtags you do not need so they will not even take up memory. Plus you only ever have one <Record> in memory anyway. If the Record tag is more complex you may want to use the XML::Rules->inferRulesFromExample() to get the rules
