Tomboy is the fourth solo album by American musician Panda Bear (aka Noah Lennox), released on April 4, 2011, initially as an online stream and later physically.

In contrast to the sample-based composition of the previous Panda Bear album Person Pitch (2007), the recording of Tomboy features a stripped-down sound built around guitar processed through Korg M3-M workstation modules.

[11] In an interview with NYCTaper in September 2010, Josh Dibb of Animal Collective revealed that he and bandmate Dave Portner had been requested to mix the album on its completion.

He noted that Sonic Boom's mix made these less obvious but "I’m hoping that those sorts of things will make it feel a little more weird, like a broadcast coming from space.

[citation needed] Rolling Stone stated that "the rapturous beauty on the Animal Collective singer's fourth solo disc is built on basic stuff: Lennox's choirboy tenor – multiplied into billowing harmonies – and sweet melodies," but called it "a bit less stunning" than Person Pitch.

"[20] According to The Quietus, the album reflected "a more streamlined assimilation of all the classic Panda Bear touchstones: 60s psych-pop, drone, techno and folk," stating that 'by shedding many of his more irksome tropes, he lets his true craftsmanship shine through.

"[28] Paste noted that the album "scales back on many of the infectious samples that made his third LP such an appealing record, instead inviting us into his own lush ambient-pop landscapes," but cautioned that Lennox occasionally "succumbs to the weight of his somewhat ambivalent, drudging experiments.

"[3] Slant Magazine claimed that "it’s difficult not to be slightly disappointed by the despondent nature of Lennox’s fourth solo album," adding that "though rich and dreamlike, Panda Bear’s latest is too tedious, too bloated, and far too serious to be anything more than an above-average record.
