Live performance skills separate the truly talented from those just getting by in a studio or band context. Take Colin Meloy, frontman with the Decemberists, for example. His album Sings Live! is a true solo project, vocals accompanied only by his acoustic guitar, recorded at assorted shows across America. With his mel-odically brisk, propulsive chords and technically excellent vocal presence, Meloy's heartfelt, direct approach suggests Brit folksingers Martin Carthy and Donovan. His set list mixes Decemberists favorites ("We Both Go Down Together"), new songs, and select covers (Pink Floyd's "Fearless"). Hear for yourself when Colin Meloy performs Wednesday, April 30, at the Fillmore at 7 p.m. Admission is $22.50; call 346-6000 or visit www.livenation.com.
