Question: Which neighborhood, located in the capital and largest city of Ethiopia, is referenced in the Bole2Harlem musical collaboration?

<P0-S0> Bole2Harlem was a musical collaboration that fused elements of Ethiopian music with American hip hop. <P0-S1>  Bole2Harlem released one album, "Bole2Harlem, Volume 1", in 2006. <P0-S2>  David "Duke Mushroom" Schommer, a producer, songwriter, and percussionist, founded the group with Ethiopian singers Tigist Shibabaw (the late sister of singer Gigi) and Maki Siraj. <P0-S3>  The project's name refers to Bole, a neighborhood in Addis Ababa (and the site of Bole International Airport), and Harlem, New York City, where Schommer and Siraj were residents. <SEP> <P1-S0> Amhara (Amharic: አማራ) is one of the nine ethnic divisions ("kililoch") of Ethiopia, containing the homeland of the Amhara people. <P1-S1>  Previously known as Region 3, its capital is Bahir Dar. <P1-S2>  Ethiopia's largest inland body of water, Lake Tana, which is the source of the Blue Nile river, is located within Amhara. <P1-S3>  The region also contains the Semien Mountains National Park, which includes Ras Dashan, the highest point in Ethiopia. <P1-S4>  Amhara is bordered by the state of Sudan to the west and northwest, and in other directions by other regions of Ethiopia: Tigray to the north, Afar to the east, Benishangul-Gumuz to the west and southwest, and Oromia to the south. <SEP> <P2-S0> Addis Ababa (Amharic: አዲስ አበባ "Addis Abäba " ] , "new flower"; Oromo: "Finfinne" , ] "Natural Spring(s)") or Addis Abeba (the spelling used by the official Ethiopian Mapping Authority), is the capital and largest city of Ethiopia. <P2-S1>  It has a population of 3,384,569 according to the 2007 population census, with annual growth rate of 3.8%. <P2-S2>  This number has been increased from the originally published 2,738,248 figure and appears to be still largely underestimated. <SEP> <P3-S0> Serejeqa (Arabic: سيريجاكا‎ ‎ , Tigrinya: ሰረጃቓ ) is a town in the Anseba Region of Eritrea. <P3-S1>  It is located about 20 km northwest of Asmara on the asphalt road to Keren, which in turn lies roughly 75 km away. <P3-S2>  The town is situated on the ridge of the Eritrean highlands. <P3-S3>  It is the upper endpoint of a gravel-road that traverses the eastern escarpments and has its other endpoint in Shebah, on the low-lying plains at the foot of escarpments. <P3-S4>  With this gravel road, Serejeqa connects the north-western part of the highlands, including the city of Keren (Eritrea's third largest city) with the Red Sea and the port of Massawa (the second largest city). <P3-S5>  This route can be traveled without having to pass through the congested capital and largest city Asmara or use the equally congested mountain-segment of the Asmara-Massawa asphalt road. <P3-S6>  Instead, the gravel road beginning in Serejeqa on one end, connects to the She'eb-Gahtelai asphalt road, which in turn unites with the less congested lowland part of the Massawa asphalt road, just 35 km from Massawa itself. <P3-S7>  Due to its proximity and connections to Asmara, Serejeqa also functions as a suburb of the capital, although it is not part of the metropolitan region of the capital (i.e. Maekel or Central Region).
