Ninja, who took the role of lead vocalist; guitarist and drummer Sam Dook; drummer Chi Fukami Taylor; bassist Jamie Bell; and musician Silke Steidinger. Steidinger was later replaced by multi-instrumentalist Kaori Tschuida in late 2005. The live band is a "separate entity" to the original studio vision, as the performances became radically different from the recordings, particularly due to Ninja's freestyled vocals over what had been instrumental studio tracks. The band's popularity increased with the re-issue of "Ladyflash" in the UK, resulting in national primetime airplay on radio stations such as BBC Radio 1, Xfm and the Atlanta, US based 99X. The song "Get It Together" from Thunder, Lightning, Strike also received popularity, being featured in trailers for the video game LittleBigPlanet. The track "The Power Is On" from Thunder, Lightning, Strike was included in "The Pitchfork 500: Our Guide to the Greatest Songs from Punk to Present." 2007–2008: Proof of Youth On 13 May 2007, The Go! Team announced the release of their new single and subsequent album on their website. The album's lead single, "Grip Like a Vice", was released on 2 July 2007, and the new album, called Proof of Youth, was released on 10 September in the UK and a day later in the US. The album featured samples and live band recordings, as well as special guests such as Chuck D, Solex, and ex-Bonde do Rolê singer Marina Ribatski. The second single from Proof of Youth, "Doing It Right", received daytime radio play from BBC Radio 1 and soundtracked the BBC's launch of the iPlayer. The album received mostly positive reviews from critics; Rob Mitchum of Pitchfork gave the album a 7.2 out of 10, expressing "Proof of Youth mostly recaptures the enthusiasm and unique sensibility of Thunder, Lightning, Strike, further filling that niche for lo-fi sample-based old-school-noise-rap we never knew we needed filling." Jeff Weiss of Stylus Magazine gave Proof of Youth a B, considering the album a "satisfying sophomore effort", but criticising the band's inability to sonically expand from Thunder, Lightning, Strike. A stand-alone single "Milk Crisis" was released via free download on 21 July 2008. They later released a 2-disc limited edition of the record with b-sides of the album including "Milk Crisis", "Phantom Broadcast", "A Version of Myself", and a remix of "Grip Like a Vice" by Black Affair. 2008–2012: Rolling Blackouts, hiatus In an interview with Stereogum in August 2008,
