This puzzle was inspired by the cover of the 1967 debut album from The Velvet Underground. The cover was designed by Andy Warhol, who chose not to put the name of the band or the album on the cover, but placed his own name in the lower right corner.
If you're wondering about the seemingly random group of given digits, the album's original running time was 47 minutes and 51 seconds.

Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box.

• Adjacent digits along a yellow line must have a difference of at least 4.
• Digits separated by a black dot are in a 1:2 ratio. Not all dots are given.
• Digits in cages sum to the number in the top-left corner of the cage and must not repeat.
• Where two cells are separated by an inequality symbol (">"), the symbol points to the lower value digit.
