Input: Consider Input: Question: Did the group that Stinson founded have more than three members? Passage:Gregory E. Stinson, better known as G. E. Stinson (born in Kingfisher, Oklahoma), is an American guitarist and founding member of new age/electronic musical group Shadowfax. Inspired by blues masters such as Bo Diddley and Muddy Waters, Stinson experimented with blues, jazz and other musical genres before co-founding Shadowfax in 1974. He remained with the band for six albums. He departed Shadowfax after recording The Odd Get Even (1989), entering the Los Angeles underground music community to refine his 'extended technique' and 'frequency manipulation'. Since then he has worked with a number of musicians on various projects, including Napalm Quartet, Splinter Group, Stinkbug, Metalworkers, Alex De Grassi, Devin Sarno and others. In 2000, he collaborated with drummer Gregg Bendian, violinist Jeff Gauthier, and bassist Steuart Liebig on an album of collective improvisational pieces recorded live in the studio, entitled Bone Structure. Released in 2003, it was given four stars by Jim Andrews in DownBeat magazine.

Input: Consider Input: Question: Who were the other members of the band that Patrick and Bill both left? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

Input: Consider Input: Question: How long had the umpire supervisor been in his position when Game 2 of the 2005 ALCS took place? Passage:Eddings was the home plate umpire for Game 2 of the 2005 ALCS between the White Sox and the Angels. White Sox batter A. J. Pierzynski quickly got two strikes and then swung at the third pitch, a splitter which came in very low. Angels catcher Josh Paul caught the ball so "thought the inning was over." Not hearing himself called out, Pierzynski took a couple of steps toward the dugout, then turned and ran to first base while most of the Angels were walking off the field. Eddings ruled that the ball had not been legally caught (an uncaught third strike), but made no audible call that the ball hit the ground. Joe Buck and Tim McCarver, announcing the game on Fox and reviewing replays of the pitch, felt the ball had clearly been caught; note that MLB did not adopt review via instant replay until the season. A pinch runner for Pierzynski subsequently scored the winning run of the game for the White Sox. According to umpire supervisor Rich Rieker, the replays showed "there was definitely a change in direction there" indicating the ball touched the ground and felt, at best, the replay was inconclusive. After the game, Eddings said he would adjust his umpiring style to clarify a third strike call from calling the batter out.
