2011 album Clancy's Tavern, and made a cameo appearance at one of Keith's concerts in July 2017. In 2018, Raven released a bluegrass album called All Grassed Up, which features a mix of new songs and re-recordings of existing material, with accompaniment from the bluegrass band Carolina Road. Musical styles Raven's musical style is defined largely by his strong influence of Cajun music, along with his lyric-driven songs and distinct vocal delivery. According to Raven, he drew musical influence from his father, who largely listened to country music, but he also drew influence from the prominence of Cajun music in his native Louisiana. An uncredited 1984 article in The Tennessean stated that Raven's style at the time was "characterized by his emotive vocals and musical as well as lyrical hooks." Thomas Goldsmith in The Encyclopedia of Country Music wrote that Raven's style was defined by "direct, soulful singing, skillful songwriting, and Cajun heritage." Many of his songs have also displayed influences of reggae and Caribbean music, such as the reggae-influenced guitar riffs played by session guitarist Reggie Young on "I Should've Called", and the "Caribbean sway" described by Newport News Daily Press writer Billy Warden in a review of "Joe Knows How to Live". Joe Edwards of the Associated Press said that Raven "has a deep, masculine voice that pours out incisive songs in a style he describes as 'Cajun reggae, Cajun Caribbean, electric Cajun.'" Similarly, Susan Beyer wrote in a review of Right for the Flight that "[h]is voice has a soulful edge, with a nice strip of grit right in the middle" and said that "instead of whomping us from the first beats with accordions and Cajun calls, he finds the delicacy in the Cajun legacy." Influence on other artists Several of Raven's compositions were successful for other artists. Among his early successes as a songwriter were four top-ten hits between 1971 and 1975: "Country Green" and "Touch the Morning" both by Don Gibson, "Sometimes I Talk in My Sleep" by Randy Cornor, and "I Don't Wanna Talk It Over Anymore" by Connie Smith. Two cuts from Eyes were later recorded by other artists: Merle Haggard covered "Dealin' with the Devil" on his 1981 live album Rainbow Stew Live at Anaheim Stadium, and Waylon Jennings covered "Sweet Mother Texas" on his 1986 album of the same name. In addition, The Oak Ridge Boys reached top five on Hot
