Sometimes a new artist nails their sound right out of the gate. I don’t think Courtney Barnett’s ever topped her debut single “Avant Gardener,” a fuzzy blend of Barnett’s expert comic timing and throwback alt-rock riffage. On the other hand, sometimes a veteran band comes off a 10-year hiatus with possibly their best record ever. (Actually, that’s probably only happened once, when No Cities To Love was, unexpectedly, everything I want a Sleater-Kinney album to be.) Indie rock will never die, just breathe new life into old grooves, as The Horrors and King Gizzard do with the sturdy motorik rhythm.
