It looks like Guns N' Roses will be back touring again in some form and you can bet that one of the songs they play is "Welcome To The Jungle" from the band's first album. Here's an interesting version where you just hear the vocals and Steven Adler's drums. During the various interludes, solos and bridge you'll also hear some guitars, but it's mostly Izzy Stradlin's parts instead of Slash.
Here's what to listen for.
1. The snare drum has a fairly long slightly delayed reverb. It's pretty dark so it blends into the rest of the mix and just acts like a glue for the part.
2. The vocal has a shorter, wider gated reverb (sounds like a Lexicon 480) with a longer predelay and more upper midrange. It's also filtered differently so there's not much bottom on it. Again, this is designed to blend into the track more to give it a sheen rather than stick out.
3. There's a lot more cowbell in this song than I remember.
4. Listen to the rhythm guitar parts at 1:40 and 2:40. There are two different complimentary parts that are split left and right that you normally don't hear clearly in the final mix.
