: The song follows a multi-part structure, typical of progressive rock, blending folk-influenced acoustic sections with driving rock rhythms. 3. Production & Remastering

: The full album version clocks in at approximately 8 minutes and 30 seconds .

: Rick Wakeman, who had recently joined the band before Fragile , contributed extensive Hammond organ and Moog synthesizer layers, adding to the song’s symphonic texture. 2. Lyrics & Themes

: The lyrics reference "mountains coming out of the sky" and "driving through the sound" of the Scottish Highlands.

The track is celebrated for its complex structure and virtuoso performances:

: Chris Squire’s bassline is widely considered legendary. Using a Rickenbacker 4001S , a pick, and low action, he achieved a punchy, "clanky" tone that cuts through the mix.

: While a shortened 3-minute radio edit was the version that reached No. 13 on the US Billboard charts in 1972, the full remaster is the preferred version for audiophiles. 4. Cultural Impact

Written by Jon Anderson and Steve Howe, the lyrics were inspired by a scenic van ride from Aberdeen to Glasgow, during which the band encountered numerous roundabouts.
