 The current lineup features Corgan, Chamberlin, Iha and guitarist Jeff Schroeder.Disavowing the punk rock roots of many of their alt-rock contemporaries, they have a diverse, densely layered, and guitar-heavy sound, containing elements of gothic rock, heavy metal, dream pop, psychedelic rock, progressive rock, shoegazing, and electronica in later recordings.Corgan is the group's primary songwriter; his musical ambitions and cathartic lyrics have shaped the band's albums and songs, which have been described as "anguished, bruised reports from Billy Corgan's nightmare-land".
