Passage: It opens with two club-driven tracks: an interlude titled "Bridge to the Sky", and the promotional titular song. "Disco-munication" is the second interlude on the album, blending "sophisticated" electric guitars with electronic music. "Energize" is another electronic track, and is one of the only numbers on the album that include English phases ("Put your hands up together, keep your heads up forever, let me sing forever,"). The fifth track "Sparkle" was noted as a club song with an electronic arrangement, similar to the follow-up song "Rollin'". Both tracks feature autotune and vocoder pro-tools, a first for Hamasaki. The album's sixth track, "Green", shows a departure from the album's earlier electronic style; it focuses more on older traditional Japanese sound, alongside instrumentation of electric guitars and drums. The album's third interlude, "Load of the Shugyo", was described as an "atmospheric" number with heavy rock instruments in its composition. Rock music is then influenced on the following tracks "Identity"—a song that discusses about self-confidence—the single "Rule", and the tune "Love 'n' Hate", which talks about the effects of lust. The album's fourth and final interlude "Pieces of Seven" was noted for its "atmospheric" sounds of an ocean, until the second half of the track diverges into a harder rock style. "Days" is the album's first pop ballad, and is described as a love song. It closes with the ballad "Curtain Call", which features a choir and piano riffs throughout its composition.

What's an instrument strongly associated with the traditional music found in the album's sixth track?

Passage: The same year, Krichell went to Hartford, Connecticut to sign shortstop Leo Durocher for a $7,500 bonus ($ in 2010). When the deal was concluded, Barrow sent Krichell to Salt Lake City to watch young second baseman Tony Lazzeri, who played for the Salt Lake Bees of the Pacific Coast League and hit 60 home runs and achieved over 200 RBIs the previous season. The Bees were asking for $50,000 ($ in 2010), but several scouts placed his value ten times lower. The Chicago Cubs were given the option to sign him for a discounted rate, but declined because he had epilepsy. Krichell saw promise in the player and convinced Barrow to buy him. Around the same time, he helped acquire shortstop Mark Koenig from the Minneapolis Millers. These Krichell signings formed part of the 1927 New York Yankees team, considered by many to be the greatest team ever assembled. Four of the starters in this squad were signed by Krichell, including three-quarters of its infield and Mike Gazella, its main backup, who signed for $500 in 1923 ($ in 2010). The Yankees took just four games to defeat the Pittsburgh Pirates and win the 1927 World Series.
