Peng! Was the debut album by Stereolab. It was originally released in 1992. It featured all the hallmarks of their sound which was driven by rhythm guitar, vintage keyboards, a motorik beat and Laetitia Sadier’s part-Nico-part-ethereal vocals. They were influenced as much by the sunshine pop of The Free Design as the were the experimental rock of Can. This is good place to start with the ‘lab, as well as being a cracker, you can see how their sound progresses from here, album by album.
