I've found some older tracks with drums, but they're usually at the end of albums after listening to 30+ minutes of music which has some impact! But, yeah, I was worried people wouldn't study the genre enough if they didn't know it already. There are many modern tracks with percussion, but its often used very sparingly. Or totally washed out with reverb (dry 0% / wet 100%). I think drums can be fine, but dance/rock beats are definitely too much in the tradition of the genre.
