providing a more considered side

[Vladv1]

"Back Street Crawler were a far more earnest proposition musically than The Kids, but in Terry Slesser they again had a frontman whose gravelly vocals and hard-man onstage image would have made a fine complement to Bon’s own tough-guy persona, their signature song, .‘It’s A Long Way Down To The Top’, providing a more considered side of Bon’s similarly titled tale. But the band, though intent on continuing with a new guitarist, Geoff Whitehorn, had not had time to bed in yet. Kossoff was just 25 when he died. Rather than share the shock and sadness of his death though, both Bon and the brothers were mightily pissed off".
Mick Wall, "Hell Ain't A Bad Place To Be".

What does "providing a more considred side" mean here in other words? https://genius.com/Ac-dc-its-a-long-way-to-the-... the Bon's song (tale). The titiles are almost similar.
