Problem: Background: The Smashing Pumpkins (or Smashing Pumpkins) are an American alternative rock band from Chicago, Illinois. Formed in 1988 by frontman Billy Corgan (lead vocals, guitar) and James Iha (guitar), the band included D'arcy Wretzky (bass guitar) and Jimmy Chamberlin (drums) in its original incarnation. It has undergone many line-up changes over the course of its existence, with the current lineup being 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.
Context: On his birthday on March 26, 2016, original guitarist James Iha joined Billy Corgan, Jimmy Chamberlin, and Jeff Schroeder on stage unannounced at the Ace Hotel in downtown Los Angeles. He performed a few songs, including "Mayonaise", "Soma" and "Whir" marking his first appearance with the Smashing Pumpkins in 16 years. Iha also played at the second of the two Smashing Pumpkins shows at the Ace Hotel the following day, which was Easter Sunday. Iha joined the Pumpkins for a third time at their April 14 concert at the Civic Opera House in Chicago. In July, Corgan began hinting of the possibility of reuniting the band original lineup, of himself, Iha, Wretzky, and Chamberlin, and in August, he stated he had begun reaching out to the original lineup about the feasibility of a reunion, including speaking to Wretzky for the first time in sixteen years. Despite the comments, Corgan would spend much of 2017 working on solo material - recording and releasing the solo album Ogilala and beginning work on another solo album for 2018. In June 2017 Chamberlin also mentioned the possibility of a reunion tour in 2018. In January 2018 Corgan shared a photo of himself, Iha, and Chamberlin together in recording studio. In February 2018 Corgan announced that he was working with music producer Rick Rubin on a future Smashing Pumpkins albums, that there were currently 26 songs he was actively working on, and that "the guitar feels once again like the preferred weapon of choice." Soon afterwards, Corgan shared a photo of sound equipment with Iha's name on a label, as well as announcing recording was finished on the upcoming album.  On February 15, 2018, the band officially announced that founding members Iha and Chamberlin were back in the band. They will embark on the "Shiny and Oh So Bright Tour" starting in July, with a focus on performing material from their first five studio albums. Original bassist D'arcy Wretzky claimed she had been offered a contract to rejoin the band but Corgan rescinded the offer soon after. Corgan released a statement denying the claims, stating "Ms. Wretzky has repeatedly been invited out to play with the group, participate in demo sessions, or at the very least, meet face-to-face, and in each and every instance she always deferred". Jack Bates (son of Joy Division bassist Peter Hook) will play bass on the tour. Bates previously toured with the Smashing Pumpkins in 2015.  In March 2018, Corgan mentioned the band planned to release two EP's in 2018, with the first tentatively planned for May.
Question: Have they done any recent tours?
Answer: Jack Bates (son of Joy Division bassist Peter Hook) will play bass on the tour. Bates previously toured with the Smashing Pumpkins in 2015.

Problem: Background: The Macedonians (Greek: Makedones, Makedones) were an ancient tribe that lived on the alluvial plain around the rivers Haliacmon and lower Axios in the northeastern part of mainland Greece. Essentially an ancient Greek people, they gradually expanded from their homeland along the Haliacmon valley on the northern edge of the Greek world, absorbing or driving out neighbouring non-Greek tribes, primarily Thracian and Illyrian. They spoke Ancient Macedonian, a language closely related to Ancient Greek, perhaps a dialect, although the prestige language of the region was at first Attic and then Koine Greek. Their religious beliefs mirrored those of other Greeks, following the main deities of the Greek pantheon, although the Macedonians continued Archaic burial practices that had ceased in other parts of Greece after the 6th century BC.
Context: Both Strabo and Thucydides said that Emathia and Pieria were mostly occupied by Thracians (Pieres, Paeonians) and Bottiaeans, as well as some Illyrian and Epirote tribes. Herodotus states that the Bryges were cohabitants with the Macedonians before their mass migration to Anatolia. If a group of ethnically definable Macedonian tribes were living in the Pierian highlands prior to their expansion, the first conquest was of the Pierian piedmont and coastal plain, including Vergina. The tribes may have launched their expansion from a base near Mount Bermion, according to Herodotus. Thucydides describes the Macedonian expansion specifically as a process of conquest led by the Argeads:  But the country along the sea which is now called Macedonia, was first acquired and made a kingdom by Alexander [I], father of Perdiccas [II] and his forefathers, who were originally Temenidae from Argos. They defeated and expelled from Pieria the Pierians ... and also expelled the Bottiaeans from Bottiaea ... they acquired as well a narrow strip of Paeonia extending along the Axios river from the interior to Pella and the sea. Beyond the Axios they possess the territory as far as the Strymon called Mygdonia, having driven out the Edoni. Moreover, they expelled from the district now called Eordaea the Eordi ... The Macedonians also made themselves rulers of certain places ... namely Anthemus, Grestonia, and a large part of Macedonia proper.  Thucydides's account gives a geographical overview of Macedonian possessions at the time of Alexander I's rule. To reconstruct a chronology of the expansion by Alexander I's predecessors is more difficult, but generally, three stages have been proposed from Thucydides' reading. The initial and most important conquest was of Pieria and Bottiaea, including the locations of Pydna and Dium. The second stage consolidated rule in Pieria and Bottiaea, captured Methone and Pella, and extended rule over Eordaea and Almopia. According to Hammond, the third stage occurred after 550 BC, when the Macedonians gained control over Mygdonia, Edonis, lower Paeonia, Bisaltia and Crestonia. However, the second stage might have occurred as late as 520 BC; and the third stage probably did not occur until after 479 BC, when the Macedonians capitalized on the weakened Paeonian state after the Persian withdrawal from Macedon and the rest of their mainland European territories. Whatever the case, Thucydides' account of the Macedonian state describes its accumulated territorial extent by the rule of Perdiccas II, Alexander I's son. Hammond has said that the early stages of Macedonian expansion were militaristic, subduing or expunging populations from a large and varied area. Pastoralism and highland living could not support a very concentrated settlement density, forcing pastoralist tribes to search for more arable lowlands suitable for agriculture.
