Glam metal bands continued their run of commercial success in 1987 with Mötley Crüe releasing "Girls, Girls, Girls", White Lion releasing "Pride", and Def Leppard releasing "Hysteria" producing a hard rock record of seven hit singles. Another of the greatest successes of the era was Guns N' Roses, originally formed from a fusion of bands L.A. Guns and Hollywood Rose, who released the best-selling début of all time, "Appetite for Destruction". With a "grittier" and "rawer" sound than most glam metal, incorporating elements punk, blues and thrash, Appetite For Destruction produced three top 10 hits, including the number one "Sweet Child O' Mine". Duff McKagan was in the hard-core band, The Fartz, prior to joining Guns N' Roses. Such was the dominance of the style that Californian hardcore punk band T.S.O.L. moved towards a glam metal sound in this period. Also in 1987, L.A. band Faster Pussycat released their debut self-titled album eponymous début and Dokken released the successful "Back for the Attack".
