Bonus round!
By 2005, many years had passed since the grunge era, and I think people were once again ready for some guitar-heavy classic rock sounds. And the 3 guys from Australia called Wolfmother were ready to supply it. They brought psychedelic rock and 70's classic rock to the aughts, with some style, talent, soaring vocals, and imaginative lyrics.
They stuck around for a while, and went through many different incarnations, but I prefer the original lineup that produced their self-titled debut, which was released in the US in 2006. It seemed to come out of nowhere, and was packed with hit songs. It generated no less than 6 singles, including Mind's Eye, Love Train, and all these
Wolfmother – Dimension
Wolfmother – White Unicorn (live)
Wolfmother – Woman (live on Letterman)
Wolfmother – Joker & the Thief (compilation with Johnny Knoxville)
Their subsequent releases make me think of the band Boston - not bad, but not different enough (or better enough) to be notable.
