The Osheaga lineup for 2013 is jam-packed with awesome acts, but, sadly, you won't be able to see them all.

The festival at Montreal’s Parc-Jean Drapeau on Ile Ste-Hélène runs for three days from Friday Aug. 2 and to the night of Sunday Aug. 4, but with more than 100 artists performing there just won't be enough time to fit them all in.

No worries. HuffPost has compiled a list of the must-see acts and lesser-known artists each day that you need to see.

Check it out, and other notable Osheaga acts, in the slideshow below.
