Hinder
Hinder is an American rock band from Oklahoma City, Oklahoma that was formed in 2001 by lead singer Austin Winkler, guitarist Joe "Blower" Garvey, and drummer Cody Hanson with bassist Mike Roden and guitarist Mark King, joining in 2003, solidifying the line-up. The band released four studio albums with Winkler; "Extreme Behavior" (2005), "Take It to the Limit" (2008), "All American Nightmare" (2010) and "Welcome to the Freakshow" (2012). Cody Hanson, along with former lead singer Austin Winkler, wrote the majority of the band's music on their first four albums. After Winkler left the band in 2013, they looked for a new lead vocalist, and added Marshal Dutton. They have since released: "When The Smoke Clears" (2015) and "The Reign" (2017) with their new vocalist. Their seventh studio album is expected in 2020. The band was inducted into the Oklahoma Music Hall of Fame in 2007.
Hinder
Before the band formed, Bryce Hinder sang in an Oklahoma City cover band until July 2001, when he met drummer Cody Hanson and lead guitarist Joe Garvey at a college party. Soon after meeting, the three formed Hinder. Hanson commented on Austin Winkler shortly after the band formed saying he was "blown away" and "he has the kind of charisma very few people have and that unique voice. You can't really compare him to anybody." After recruiting bassist Cole Parker, they recorded a 4 track demo disc, with the track listing "Someday", "Like Me", "Broken", and "Worthless Home". The tracks "Someday" and "Broken" would later be re-recorded and put on their debut EP "Far From Close" and the other two tracks "Like Me" and "Worthless Home" still remain unreleased, only being able to find them on their demo CDs, although they are now posted on YouTube. The band began performing at an Oklahoma City club called The Blue Note, building a local fan base. Profits from the shows went to advertising, as well as paying the expenses for the group's first release. In April 2003, Hinder entered the March Bandness contest for Oklahoma City radio station KHBZ-FM (94.7). They made it to the Final Four out of a field of thirty-two, ultimately losing to the OKC group Falcon Five-O. After saving enough money from local concerts the band's debut EP "Far From Close" was released in 2003 on the independent label Brickden Records and sold around 5,000 copies. Bassist Mike Rodden was recruited from Oklahoma City band Shade Seven and rhythm guitarist Mark King joined the band later that year.
