I'm not sure if you guys listen to this show, but if you do, what are your some of your favorite essential mixes? For those that aren't familiar with it, it's a British radio show that hosts a ton of different famous and upcoming DJs and producers to come and play (they also play live sets from gigs as well). Its been running since 1993. I really like listening to this radio show since they invite all sorts of artists to play from a wide range of genres, such as trance, house, progressive house, experimental, drum and bass, etc.

For me, my favorite trance essential mixes are Paul Oakenfold's from Rojam, Shanghai 1999 and Above and Beyond's from 2004. For progressive house and house, I really like Deep Dish from Space Ibiza in 2005 and John Digweed''s from Manchester Warehouse in 2007.
