On Friday, Tame Impala will play their third show in Colorado in just under 2 years to a sold-out crowd at The Ogden in Denver. One of the most anticipated spring Denver concerts is, however, unlikely to be an outlier for the group on their North American tour – all but 4 of its shows have sold out. So the story goes for one of the more prolific indie groups in recent years.

Initially the brainchild of frontman Kevin Parker, it can be difficult to figure out just what Tame Impala is anymore. Is it a still solo project? Are they now a band? Parker still handles the bulk of the studio recording, but with input from drummer/keyboardist/backing vocalist Jay Watson and bassist/guitarist/percussionist Dominic Simper. And even with the three of them, it would be impossible for the music to come to life in a concert setting without the rest of their bandmates Julien Barbagallo and Cam Avery, also members of Pond, a psych-rock outfit oft associated with Tame Impala.

And though Kevin may be getting more help in the studio these days, it wasn’t always that way. The very first Tame Impala songs were recorded solely by the Aussie for nothing other than pure enjoyment before he was picked up by Modular, and Watson and Simper were featured in just two songs on their stellar 2011 debut. Though their roles may be larger than ever, it appears as though Kevin remains in full control of the group’s sound, which he aims to steer in a new direction on their upcoming Currents.

Parker has stated that pop-rock legends Supertramp are one of the major influences on Tame Impala, and that influence is more apparent than ever on their recent single “Cause I’m a Man”. Bearing resemblance to Lonerism’s lazy chilled out pop hit “Feels Like We Only Go Backwards”, the song is an even greater departure from his early work.

This will likely be a theme with upcoming Tame Impala releases, as the synthy prog-pop “Let It Happen”, the longest song on Currents, seems to be the closest Parker is willing to get his heavy psych-rock roots. The newer, poppier sound might put off some of the band’s earliest fans, but it has won over critics and fans alike.

It should be interesting to see how Friday’s show plays out. I caught them at Boulder Theater the last time they came to town and was thoroughly impressed. As one who admittedly prefers the psych-rock side of Tame Impala, their Lonerism-heavy set was surprisingly jammy and incredibly fun, as barefooted Kevin kicked around bouncing balloons and played a solo with a toy kazoo, items smuggled in and thrown on stage by eager fans.

Lots of new material can probably be expected, as the group hasn’t exactly been shy about sharing their work on Currents, releasing 4 of its tracks in just under 3 months. Look for up-and-coming MGMT-affiliated psychedelic pop-rockers Kuroma to open and set the tone for a fun night of great music early.
