Ask and you shall receive. As I have explained to many, many people, Drum & Bass is a massive genre (possibly the largest in all of EDM) with so many styles and sub genres. You could ask 10 different "Junglists" what D&B was to them and each would probably give you a different definition from the other. So this is my very subjective list of where to start, not in any particular order either.
Calibre - Setting Sun (2005)
http://www.discogs.com/Calibre-Second-Sun/master/118846
Calibre is possibly one of the top ten most prolific producers in D&B. He releases a staggering amount of material on a monthly basis. This was his second album. He created this very stripped down minimal groovy sound that almost no one can duplicate correctly.
High Contrast - High Society (2004)
http://www.discogs.com/High-Contrast...y/master/37961
High Contrast helped turn a very small disco infused sub genre called Liquid Funk into one of the biggest in all of drum & bass. This producer also turned a little label called Hospital Records into arguably the most successful today. This is his second album. it was really hard for me to decide which to recommend because they are all very good but I'd start with this one for a novice. His music is very melodic and has lots of soul and uk urban influences in it.
Ed Rush and Optical - Worm Hole (1998)
http://www.discogs.com/Ed-Rush-Optic.../release/22025
Ed Rush and Optical championed a sound called Neurofunk. It’s very minimal and often darker sounding with swirling basslines
Calyx + Teebee – Anatomy (2007)
http://www.discogs.com/Calyx--Teebee...y/master/29834
Neurofunk changed and mutated over the years and eventually started to sound like this. It’s very good but also dark, evil, brooding sounding stuff.
Netsky – Netsky (2010)
http://www.discogs.com/Netsky-Netsky/master/252631
This 21 year old Belgian kid went from total obscurity 12 months ago into one of the hottest new producers in D&B. He is kind of taking the Liquid Funk genre into a totally new realm and some are calling him the next High Contrast.
Commix - Call To Mind (2007)
http://www.discogs.com/Commix-Call-T.../master/103483
Often voted as the best D&B album of 2007 if had a few huge hits on it like a track called Be True which you heard in practically every DJ set for a good 6 months to a year.
Danny Breaks – Vibrations (2002)
http://www.discogs.com/Danny-Breaks-.../master/128505
No one else sounds like this guy. He took lots of weird minor key melodies and sci-fi sounding samples and created some of the most interesting drum & bass ever in my opinion. He’s also a world class turntablist and has since gone on to producing straight instrumental hip-hop.
Goldie – Timeless (1995)
http://www.discogs.com/Goldie-Timeless/master/184569
One of the first true d&b albums. This was massive when it came out. It had a huge effect on practically every producer for the next decade.
Jonny L – Sawtooth (1997)
http://www.discogs.com/Jonny-L-Sawtooth/master/11674
Jonny L has been around forever and gone through a ton of different styles within D&B. This album came out around the time a genre called Tech-Step was starting to emerge. It’s very similar to Neurofunk which it sort of merged with eventually.
Logistics – Now More Than Ever (2006)
http://www.discogs.com/Logistics-Now.../master/131153
Logistics is another favorite producer of mine. He’s also quite prolific. This was his first album which is a double CD. He also helped turn Hospital Records into a power house and brought a bit of variety to the label at the time as he was producing some harder tracks than they were previously putting out. This album helped them branch out quite a bit.
