Question: Which group did this musician from the rock band that released Zeitgeist join shortly after the its breakup?

Zeitgeist EP is the second album released by Spanish/German rock band Frogcircus.  It was released on the German label Thorshammer shortly after moving from Las Palmas de Gran Canaria (Spain) to Berlin in early 2001. <SEP> James Joseph Chamberlin (born June 10, 1964) is an American drummer and record producer.  Following the 2000 breakup of the band, Chamberlin joined Pumpkins frontman Billy Corgan in the supergroup Zwan and also formed his own group, the Jimmy Chamberlin Complex.  In 2005, Chamberlin joined Corgan in reforming The Smashing Pumpkins; he eventually left the group in March 2009, though he returned again in 2015 for a summer tour.  He performed in the group Skysaw until 2012.  He is currently active under the Jimmy Chamberlin Complex name.  In addition to his current work as CEO, Chamberlin has joined Chicago jazz saxophonist Frank Catalano for a string of 2013–15 performances in the Chicago area.  An EP by Catalano and Chamberlin "Love Supreme Collective - EP" was released on the 29th of July 2014.  He is best known as the drummer for the alternative rock band The Smashing Pumpkins. <SEP>  It was the first album The Smashing Pumpkins released after their 2000 disbandment and 2005 reunion. Zeitgeist is the seventh album by American alternative rock band The Smashing Pumpkins, released on July 10, 2007 in the United States and Canada.  The album was produced by Roy Thomas Baker, Billy Corgan, Jimmy Chamberlin, and Terry Date.  The album would be Chamberlin's last with the band before his departure in 2009.  The album debuted strongly, but sales soon decreased, and critical reception was mixed.  It was certified Gold in the United States on February 1, 2008. <SEP> The Hangmen were an American garage rock band from Rockville, Maryland who were active in the 1960s.  In an effort to distinguish themselves from other American groups and tie-in with the popular British Invasion, they lured Scottish vocalist Dave Ottley to join the group.  Eventually they became the most popular band in the Washington, DC area, having a huge regional hit with "What a Girl Can’t Do", that appeared on Monument Records, but had actually been recorded by an earlier local group, the Reekers, whose membership included two future Hangmen, Tom Guernsey and Bob Berberich.  The single was nonetheless credited to the Hangmen.  The song became so popular that the band was greeted with near "Beatlemanic" adoration from fans, whose enthusiasm on one occasion erupted into a near riot.  The group followed-up with the single "Faces", which featured more aggressive sound, replete with a snide vocal from Ottley and a razor-like fuzz-driven guitar riff.  Ottley shortly thereafter departed from the band and was replaced by Tony Taylor.  The group, now with Taylor, went to Nashville to record the album "Bittersweet", which displayed a more eclectic and relaxed approach, which, despite its closing song, a raucous version of Van Morrison's' Gloria", stood in marked contrast to their previous efforts.  The album's opening cut was sitar-embellished version of "Dream Baby, which was also released as a single.  After additional rounds of lineup changes and in an effort to emphasize their increasingly psychedelic orientation, the Hangmen changed their name to the Button.  As the Button, they taped an unreleased set of songs for RCA Records in New York, but subsequently changed their name to Graffiti and recorded briefly for ABC Records.
