Bloody hell, I don't even remember making this thread. Rum you are a strange mistress. Thankfully it's not embarrassing.
Run The Road is a good introduction album, it's got a lot of the big names like Roll Deep, Kano, Dizzee Rascal, Tinchy Stryder and Lady Sovereign early on in their careers. It has been criticised for showcasing the side of grime closest to hip-hop and not the elements closer to its roots in UK garage though. I could really use more mixes myself, pretty much everything I have is individual artists' mixtapes although with grime sometimes it's rarer to find a track that isn't collaboration than one that is so that means a ton of people turning up. I've no idea how functional this is outside the UK but BBC 1Xtra do some shows that feature grime you can listen to on the iplayer
here (look for anything that says UKG like Cameo's show, there will be a lot that isn't grime like garage and bassline but it will rear it's head). The problem I have with those kinds of mixes is I play them when I'm drinking and hanging out since it's good party music, but then I don't pay any attention to what tracks are actually being played. But like I said I'm really out of the loop with this music at the moment, so if anyone knows good mixes I'd love to hear them myself.
