From the mid-2000s, Dr. Dre has taken on a more soulful production style, using more of a classical piano instead of a keyboard, and having claps replace snares, as evidenced in songs such as Snoop Dogg's "Imagine" and "Boss' Life", Busta Rhymes' "Get You Some" and "Been Through the Storm", Stat Quo's "Get Low" and "The Way It Be", Jay-Z's "Lost One", Nas' "Hustlers", and several beats on Eminem's Relapse album. Soul and R&B pianist Mark Batson, having previously worked with The Dave Matthews Band, Seal and Maroon 5 has been credited as the architect of this sound. Besides Batson, Aftermath producer and understudy of Dre's, Dawaun Parker, who has named Q-Tip and J Dilla as his primary influences, is thought to be responsible for giving Dre's newest beats an East Coast feel.
