What are some singers/bands that you have everything or as close to everything as you can by? Name no more than ten. Here is mine
Elvis Presley James Brown Otis Redding Hank Williams Sr. Led Zeppelin Jimi Hendrix Robert Johnson Rolling Stones Johnny Cash Iron Maiden
Many more, but I have to follow my own rules.
Northern Exposure is probably the greatest ever example of the Progressive TRance genre. I've seen them both multiple times.
I think the first NortherncExposure is very important for how groundbreaking it was at the time, but I think the greatest example is Northern Exposure: Expeditions. I think that's really the peak of the genre in the 90s.
