Tame Impala is probably my favorite band from Perth. Their 2010 album Innerspeaker is awesomely atmospheric and listenable the whole way through, and now they've got a new one out, Lonerism. Everyone's all Elephant is the jam, and it has the trippier video, but I think it's Apocalypse Dreams.
Listening through a cloud of cannabis isn't my thing, but Tame Impala is great driving around on a sunny day tripping on being alone (as the album's title suggests), spacing out, and soaking up fuzzy, vintage guitar sounds.
