Ecstasy-fuelled rock band, endless energy, very imposing (10)

I believe the answer is:
statuesque
'imposing' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for statuesque that I've seen before include "(Of a woman) tall and dignified" , "imposing" .)
I've seen this clue in The Independent.
