Alternative Christian rockers Skillet strike a balance between metalfest headliners and the worship band stage, delivering hard-charging anthems for secular and spiritual audiences alike. Slowly amassing an audience in the mid-'90s, they beefed up the band's lineup and broke into the mainstream in 2001 with their fourth album Alien Youth. From there, the quartet experienced a quick ascent on the charts, rapidly increasing in popularity with each successive release. By 2009, they had reached number two on the Billboard 200 with their best-selling effort to date, Awake. Subsequent LPs Rise (2013) and Unleashed (2016) proved just as popular, attracting a diverse audience with their reliably propulsive and riff-heavy output.
