Consensus is that Turbonegro peaked with 1998’s “Apocalypse Dudes” and have been delivering ever-diminishing returns since then. There might be some truth to that but since “RocknRoll Machine is the band’s fifth studio album since then, that’s a lot of backsliding over 20 years.
Let’s cut the Denim Demons some slack here. “Dudes” was a masterpiece, a clever and visceral cop of many of rock’s great moments, unashamedly woven into a punk-glam merkin and proudly worn in public. You liked “Ass Cobra” better? Buy yourself a sailor hat.
“Self-parody” is a term many reverred acts have had thrown at them - often by critics who can’t abide a band playing to its own strengths, or not knowing that a purple patch of three or four consecutive great albums is a rarity for a long-running outfit. Just ask the Ramones- if you can find one still living) - or the Cramps (although they did morph into something approaching a conventional rock band.)
