Gibson continues their countdown of the Top 50 American Rock Bands of All Time. Today they disclose their picks for No 31-40. Here are a couple highlights:34. Pixies: If all the Pixies had done was make great music that was well-received by audiences, they'd already deserve a place on this list. Songs like "Here Comes Your Man," "Monkey Gone to Heaven," "Where is My Mind?," "Cactus" and "Debaser" will forever hold a place in the rock Pantheon. But they deserve further kudos for influencing the quiet verse/loud chorus dynamic of later bands such as Nirvana, who were unashamed of their direct referencing of Pixies song structures. – Peter Hodgson
33. X: X formed in 1977 during the first wave of punk, and later diversified their sound in more rock-based directions. The band is known for their powerful live shows, and was officially recognized by the City of Los Angeles for their contributions to L.A. music and culture. Despite a number of break-ups and reunions, the band is still going strong, although talk of songwriting sessions by vocalist Exene Cervenka and vocalist/bassist John Doe in 2008 has not yet translated into a new album. – Peter Hodgson Check out the full list here
