The two women, who slipped into the country on a surprise visit, met with US lawmakers as well as White House and State Department officials in a bid to publicize their friends' plight and press for their freedom.
Maria Alyokhina, 24, and Nadezhda Tolokonnikova, 23, are being held in two separate Russian penal colonies after being sentenced to two years in prison in August for hooliganism motivated by religious hatred.
The sentences, handed down after the balaclava-wearing band of rockers performed a protest song against Russian President Vladimir Putin in an Orthodox Moscow cathedral, have attracted global attention and condemnation.
The visiting band members, who wanted to be known by the pseudonyms Fabra and Shaiba, today shed their brightly-colored headgear, revealing their faces at a small press conference.
But they asked that no pictures or video be taken of them, and their voices modified in audio-tapes, fearful of repercussions by the Russian authorities.
"We came to Washington DC specifically... To meet with several members of Congress and politicians to discuss our situation," Shaiba said. "We asked them for their help."
The women urged the US to raise their case directly with Putin and Russian authorities, and seek to visit Alyokhina, who has just ended an 11-day hunger strike, and Tolokonnikova in the prison colonies where they are held.
It was "very important" for foreign governments and the media to keep a spotlight on the issue "because it doesn't allow the government to get out of control and it actually forces them to be more careful and attentive towards the laws of the Russian federation," Shaiba said.
Out of safety concerns, the two women refused to say how they arrived in the United States, their future plans and if they would visit other countries.
