Mac Miller made it to the top of the Billboard album chart as a rapper, but his Twitter bio reads "I Make Sick Beats," and mentions nothing of lyrics. Maybe the background is more important than the foreground for the Pittsburgher these days. Early this morning, he put up Volume 1 of an instrumental mixtape series he's doing under the moniker "Larry Fisherman." In fact, on a few of the tracks, you'd have to stretch your ear to imagine this music as the output of someone really even that interested in rap, since they're indebted to ambient lounge music than anything else.
