Task: Question Answering
Input (English): Passage: In 2003, The Greencards recorded and self-released Movin' On, their debut album, which sold 10,000 copies at shows and online, and entered the top five on the Americana radio charts. Pat Flynn, one of the band members of the New Grass Revival, guested on the recording of Movin' On as a session guitarist, and would return to do so again on Weather and Water. The album was said to break past traditional rules of bluegrass music by integrating a jam-band mindset while blending classical folk balladry and rock 'n' roll into the sound. Contrasting with that appraisal, the album was also cited as a traditional and successful "lo-fi" approach to bluegrass music. Critics noted the virtuoso solos on mandolin, fiddle, and guitar on Movin' On.The Greencards gained more fans and became known by name quickly after the release of Movin' On. The band was credited with performing the most energetic sets during the course of the 2004 Austin City Limits Music Festival, were said to bring a global sound to bluegrass, and—by drawing on influences such as Bob Dylan and The Beatles—were pushing the genre's boundaries. Their live show during this period was ranked by the Houston Chronicle in the top five nights of live music for the year in 2004.Movin' On earned The Greencards the 2004 Austin Music Award for Best New Band. Several months after the awards, the band was signed by Dualtone Records and began work on their next album, Weather and Water. The label re-released Movin' On at the beginning of 2005, generating still more airplay and sales. 
Question: What is the name of the group whose live show was ranked by the Houston Chronicle in the top five nights of live music for the year in 2004?
Output (English): The Greencards.
