His music was often described as combining hip hop with several other musical genres, such as blues rock and folk music.  His fusion of these genres has led many critics to compare him to Beck, and, in some cases, even say that he originated the fusion of folk and hip hop before Beck made it famous.  Others have compared him to Bob Dylan, but Sichran criticized such comparisons, saying that he would "never want [his] music to exist on comparisons to someone else."

Bob Dylan ( ; born Robert Allen Zimmerman, May 24, 1941) is an American singer, songwriter, musician, painter, and writer.  He has been influential in popular music and culture for more than five decades.  Much of his most celebrated work dates from the 1960s, when he became a reluctant "voice of a generation" with songs such as "Blowin' in the Wind" and "The Times They Are a-Changin'", which became anthems for the Civil Rights Movement and anti-war movement.  Leaving behind his initial base in the American folk music revival, his six-minute single "Like a Rolling Stone", recorded in 1965, enlarged the range of popular music. Alternative hip hop (also known as alternative rap) is a subgenre of hip hop music that encompasses the wide range of styles of hip hop that have not become identified as mainstream.  AllMusic defines it as follows: "Alternative rap refers to hip hop groups that tend not to conform to any of the traditional forms of rap, such as gangsta, bass, hardcore, pop, and party rap.  Instead, they blur genres drawing equally from funk and pop/rock, as well as jazz, soul, reggae, and even folk" Anomaly is the seventh studio album by American Christian hip hop artist Lecrae, released on September 9, 2014, through Reach Records.

The album also fared well commercially, debuting at No. 1 on the "Billboard" 200 with over 88,000 copies sold.  It also debuted at No. 1 on the Top Gospel Albums chart, marking the first time that any artist has ever topped both the 200 and Gospel charts.  "Anomaly" won Rap/Hip Hop Album of the Year at the 2015 GMA Dove Awards, and Rap, Hip Hop Gospel CD of the Year at the 2015 Stellar Awards.  Two songs earned a nomination for the 2015 Grammy Awards; "All I Need is You" was nominated for Best Rap Performance, and "Messengers", featuring For King & Country, which won Best Contemporary Christian Music Performance/Song.  Rolling Stone ranked it at No. 12 on their list "40 best rap albums of 2014". Bob Dylan (born Robert Allen Zimmerman, May 24, 1941) is an American singer-songwriter, artist and writer.  He has been influential in popular music and culture for more than five decades.  Much of his most celebrated work dates from the 1960s, when he was both a chronicler and reluctant figurehead of social unrest.  Early songs such as "Blowin' in the Wind" and "The Times They Are a-Changin'" became anthems for the Civil Rights Movement and anti-war movement.  Leaving his initial base in the American folk music revival, Dylan's six-minute single "Like a Rolling Stone" altered the range of popular music in 1965.  His mid-1960s recordings, backed by rock musicians, reached the top end of the United States music charts while also attracting denunciation and criticism from others in the folk movement. Underground hip hop is an umbrella term for hip hop music outside the general commercial canon.  It is typically associated with independent artists, signed to independent labels or no label at all.  Underground hip hop is often characterized by socially conscious, positive, or anti-commercial lyrics.  However, there is no unifying or universal theme – AllMusic suggests that it "has no sonic signifiers".  "The Underground" also refers to the community of musicians, fans and others that support non-commercial, or independent music.  Music scenes with strong ties to underground hip hop include alternative hip hop and conscious hip hop.  Many artists who are considered "underground" today were not always so, and may have previously broken the "Billboard" charts.
