This year marks the sixth anniversary of A Leg To Stand On’s (ALTSO) annual benefit,  Hedge Fund Rocktoberfest, which is fast becoming one of their most successful fund raisers to date, with more corporate sponsors signing on than ever before.

As one of Wall Street’s most popular annual events, Hedge Fund Rocktoberfest features bands whose members work in the hedge fund and finance industry. All of the five bands scheduled to perform on the main stage at this year’s event are competing to raise the most for ALTSO; vying for the lead currently are JAM Partners and The Cause.

“I’m extremely grateful to everyone who has given,” says C. Mead Welles, co-founder of ALTSO and managing partner of New York hedge fund Octagon Asset Management. “What we do has such a big impact on these children’s lives and it costs so little to do so much.” ALTSO improves the lives of children with limb disabilities in emerging countries by providing free surgeries and prosthetic limbs.

The money raised from last year’s Hedge Fund Rocktoberfest helped the charity expand its efforts and clinics in India, Bangladesh, Haiti, Nepal, Nigeria, Colombia, and Ecuador. Revenue raised this year will go toward helping level the playing field for 1,000 more children in 2010, bringing their total of children helped to nearly 6,000 in under eight years.

“The bands are working extra hard to bring in donations this year,” says Chris Heasman, a director and portfolio manager with Lazard Asset Management in New York who performs with The Subscribers, which has played at every Hedge Fund Rocktoberfest since the event began and is scheduled to perform again this year. “Sure, Rocktoberfest is about having fun, but it’s more about raising money for ALTSO so they can continue their work with children in developing countries.”

Other long time supporters of the charity include Deutsche Bank, Credit Suisse, and Jacobs Asset Management, LLC.
