A side project of singer/songwriter Andrew Mcmahon. Basicaly a solo project produced from the help of many other people including Tommy Lee on drums! Mcmahon uses his unique voice, powerful lyrics, and the heartfelt rithyms of his ever so famous piano. With a full album out now they are a great band to listen to whether your happy or sad. Basically Something Corporate with a little twist of pop flavor. For more info see Andrew Mcmahon or Something Corporate.
One hell of a kick ass side project sure to rock you. Jacks Mannequin is awsome
