Response stream events?

[devskope]

I am trying to sequentially archive (using node-archiver) a couple of remote files fetched using bent:

const appendTracks = async (archive, items) => {
 items.forEach(async (item) => {
    const beatStream = await bent(item.publicUrl)();         // mp3s **

    archive.append(beatStream, { name: item.name });

     // ********** the following doesn't seem to work ****************
    await new Promise((resolve, reject) => {
      beatStream.on('end', () => {   // is this even possible ??? 🤷🏻‍♂️
        resolve();
      });
      
      beatStream.on('error', (err) => {
        reject();
       });
    });
  });
};

archive.pipe(res);
appendTracks(archive, order.items).then(() => archive.finalize());

How do I ensure one stream is done before the next download begins?
Need to guarantee that archive.finalize() isn't fired prematurely, which is what is happening right now.
