Metaloria by Arthur Slade

When an Anvil concert hits volume eleven, five fans are thunderstruck into Metaloria — a LitRPG realm where metal gods rule, power is measured in manna and levels, and physics bow to rock. To get home, they must out-sing Blayre, an all-powerful wizard whose spells are ear-splitting songs. Video-game fantasy meets hair-metal chaos. Crank it up. Read it loud.
