August Berlin Music Events?Concerts (electronic) ?

HELLO Travellers

I am visiting Berlin for 5 day in late august (28th august onwards) .

Can anyone tell me where to get up to date information on electronic rock music or techno music events hosted in berlin ?

I was hoping to see Tangerine Dream but there was no information on their website !

I would also like to see Kraftwerk ? again not much information on their website.

I like techno as well as Electro rock etc

Please any suggestions would be helpful .

Where would info like that be advertised in berlin or online ?

ok

DANKE SCHUN

Thank You
