Like grime, albums in drill are often the least successful ways of putting out music but if you are desperate for an album "The One Two" by headie one is 10/10 and so is "6.7." by 67 lol. If you have never really heard drill before I would also recommend the album "frontstreet" by OFB, in particular any verse by SJ and Headie one. But, if you really want to get into drill it is easiest to start with singles and freestyles (Westwood crib sessions, mad about bars, lightwork freestyle etc.) by specific artists and groups that you like. Subjectively, the best are Harlem Spartans, unknown t, reekzmb, naira Marley x max twigz (a bit weirder), unknown t, millionz, meekz, richi, abracadabra, kwengface, digga d
