Lately I've been into Thomax, Marco Polo, Statik Selektah, and Black Milk. But I like many others like Alchemist, 9th Wonder, Ayatollah, Hi-Tek, Premier, Pete Rock, RZA, J Dilla, Madlib, Just Blaze, Kanye (his old stuff), Heatmakerz, Timbaland, Scram Jones.
One of my favourite beats by Thomax. Everything comes together so nicely and the sample on the hook is perfect. Heard it 30+ times and still not bored of it.
