Ayone know the wattage used at a Rock concert?

The Who's summer tour had 120,00 watts of audio power.

Well i heard some loud concerts in my day. But in 95 i was working for pro audio and i was a record holder for that year a us auto sound compition in kansas city. Our van produced 191 dbs which was a record you could her it a 2 1/2 miles away. That was 22000 watts. But as for concerts. ive worked as a sound tech and on average 30,000 or more depends on what kind of music. Ive worked with groups like Alabama and the use 40,000 watts but look at pantera who used 25,000 watts, but you have to mention a group like scorpions 60,000 watts but remember we are talking about bands that could rock 20,000 crazy fans and still could be louder. A b1 bomber her tubines can produce well over 250 dbs at half throtle witch could damage or even kill.so sound all you have to remember that 1000 watts with no obstuctions can carry to the horizon 

Agreed on Motorhead being the loudest.  I have heard AC DC, Judas Priest, Sabbath, you name them and Motorhead was the loudest.  FAR from the best, but definitely the loudest.

I saw The Who and AC/DC, but my loudest show was The Ramones in L.A. in the 90's. I can't remember the venue, but the room was all cement, the sound bouncing off the walls from every direction forever. I got SUCH a headache.
