No VH1 Storytellers, no eardrum-sparing acoustic tours: These aging Aussies still insist on rocking like teenagers. Unfortunately, even perennial schoolboy Angus Young is now 42, so listening to them shake it all night long is like watching your dad squeeze into a pair of pants that fit him 20 years ago. Angus jagged guitar riffs havent lost all their power, and Brian Johnson still wails like hes passing a Buick through his colon. But without any infectious Highway to Helllike anthems, these guys rarely sound better than an AC/DC cover band.
