British rock band Jethro Tull and Indian musician Anoushka Shankar hope to get Mumbai back on its feet with a concert on Friday, barely a week after at least 171 people were killed in militant attacks in the city.

It will be the first major concert in India's financial capital since 10 Islamist gunmen went on a three-day rampage at top luxury hotels, a railway station and a Jewish centre.

The Live Earth India concert on Dec. 7, another event featuring international artists, was called off in the wake of the attacks.

"Some people might consider it disrespectful that we are having a concert but hopefully a majority will realise what this is about and what it says," Jethro Tull frontman Ian Anderson said at a press conference.

The band, on a tour of New Delhi, Kolkata and Bangalore, was scheduled to perform in Mumbai last week. The Nov. 29 event was postponed following the attacks.

Proceeds from the Mumbai concert would go to a charity set up for victims of the attacks.

For Shankar, going ahead with the concert was a message in itself.

"As a musician, this is how I speak, how I express the anger within me," she told reporters.

"Our entire tour has been changed by these events and even though the structure of the concert may remain the same, emotionally perhaps we are saying a lot more."
