Not all Southern rock artists fit into the above molds. The Atlanta Rhythm Section (former Classics IV), the Amazing Rhythm Aces as well as Orleans were more focused on vocal harmonies, and Louisiana's Le Roux ranged from Cajun-flavored Southern boogie early on to a more arena rock sound later on, while the Dixie Dregs and Allman Brothers' offshoot Sea Level explored crossover and jazz fusion. Wet Willie, Molly Hatchet, Blackfoot, ZZ Top, Johnny Winter and Black Oak Arkansas were also popular southern rock musicians in 1970s.
