Rocks for Toronto, also dubbed SARStock, at Downsview Park in Toronto on July 30, 2003, with an attendance of over half a million people. The concert was intended to benefit the Toronto economy after the SARS outbreaks earlier in the year. The band has also sustained an interest in promoting human rights. They donated $100,000 to the Canadian Museum for Human Rights after a concert they held in Winnipeg on May 24, 2008. On July 24, 2013, Rush performed a benefit concert in Red Deer, Alberta, at the ENMAX Centrium with all proceeds going to the Canadian Red Cross to help victims of the 2013 flooding that devastated many regions of southern Alberta. The original venue for the show, the Scotiabank Saddledome, was heavily damaged from the flooding and was unavailable for the concert date as originally planned. The individual members of Rush have also been a part of philanthropic causes. Hughes & Kettner zenTera and TriAmp electronics have been endorsed and used by Lifeson for many years. A custom signature amplifier was engineered by Lifeson and released in April 2005 with the stipulation UNICEF will receive a donation in the amount of $50 for every Alex Lifeson Signature TriAmp sold. Lee, a longtime fan of baseball, donated 200 baseballs signed by famous Negro league players, including Willie Mays, Hank Aaron, and Josh Gibson, to the Negro Leagues Baseball Museum in June 2008. In late 2009, Geddy Lee and Alex Lifeson launched an auction for their initiative "Grapes Under Pressure", in support of the cause "Grapes for Humanity". The auction consisted of items from the band such as signed guitars, cymbals and basses, as well as autographs on all items by the band members. There were also autographs by band members from Depeche Mode, Tool, the Fray, Judas Priest, Pearl Jam and more, as well as signatures from Ricky, Julian and Bubbles from Trailer Park Boys on a rare Epiphone guitar. The band is featured on the album Songs for Tibet, appearing with other celebrities as an initiative to support Tibet and the current Dalai Lama Tenzin Gyatso. The album was made downloadable on August 5, 2008, via iTunes and was released commercially August 12, 2008. Rush has also been a big supporter of Little Kids Rock, a national nonprofit that works to restore and revitalize music education programs in disadvantaged U.S. public schools.
