When an artist who is already famous dies suddenly, tributes can start right away, and circulate rapidly; when a more obscure artist dies young, the tributes, and even the news of his death, can take much longer to reach people who like, or might like, his work. Take Nick Drake, so much better known now than when he was alive; or Keith Girdler, lead singer in the 1990s indie-pop act Blueboy, who died in 2007, from cancer. You wouldn't mistake Girdler's work for Drake's, but if you like one you'll probably like the other. There's the delicate voice just barely willing (he's clearly able) to lift and drop a melody; the spiderweb-thin bareness of some tracks, and the fluent chamber arrangements of others; the hint of rock and roll, usually just offstage. If Drake was a reticent hippie, Blueboy were reticent sophisticates; Girdler was confessing his quasi-secrets at the edge of a party too fancy for him, and for you, to feel comfortable there. Blueboy were in their time the best and the smartest proponents of a particular sort of mostly acoustic pop.
