Just like the organism from which it takes its name, Amoeba Music?s stock of tunes has no definite form. At each location, expert music gurus?many of them musicians themselves, all of them record-store veterans and dedicated sonic obsessives?amass thousands of new and used CDs and LPs from the most mainstream artists to the most obscure underground bands around. LPs, posters, and memorabilia surround the musical inventory, which, like Ringo Starr?s pants, changes every day. Amoeba buys goods from customers, meaning that on any given day the store might usher in a rare vinyl LP, DVD, VHS, or even LaserDisc. Visitors can sign up for any number of contests while admiring Amoeba?s enduring dedication to its green practices and community outreach. Amoeba couples its huge selection of entertainment with visits from the artists themselves, welcoming past guests such as Paul McCartney, Bret McKenzie and Jemaine Clement of Flight of the Conchords, and Elvis Costello to play in-store.
